Application of Sodium Dodecylbenzenesulphonate
Sodium dodecylbenzene sulfonate is neutral, sensitive to water firmness, challenging to be oxidized, solid foaming power, high detergency, simple to intensify with various ingredients, low cost, mature synthesis procedure, application It has a vast array of areas and also is a superb anionic surfactant. Sodium dodecyl benzene sulfonate has a considerable decontamination impact on granular dirt, healthy protein dust and oily dirt, especially for the washing of granular dirt on all-natural fibers. The effect of dirt is greater than that of nonionic surfactants, and the foam is rich.
However, salt dodecylbenzene sulfonate has 2 drawbacks. One is that it has inadequate resistance to tough water, as well as the purification efficiency can be decreased with the firmness of the water. For that reason, the detergent with its primary active agent have to be utilized with a suitable amount of chelating representative Second, the degreasing power is solid, and also it is irritating to the skin when washing by hand, as well as the garments really feel bad after washing. It is recommended to utilize cationic surfactants as conditioners for washing. In recent times, in order to get a much better extensive cleaning impact, salt dodecylbenzenesulfonate is commonly used in combination with nonionic surfactants such as fatty alcohol polyoxyethylene ether (AEO). The major use of salt dodecylbenzene sulfonate is to formulate different kinds of liquid, powder, granular detergents, cleansers and also cleaners.
An emulsifier is a substance that enhances the surface tension in between numerous constituent stages in a solution to develop an attire as well as stable dispersion system or solution. Emulsifiers are surface-active substances with both hydrophilic and also lipophilic groups in their molecules. They aggregate on the oil/water user interface, which can decrease the interfacial stress and also decrease the power needed to form a solution, thereby enhancing the power of the solution. As an anionic surfactant, salt dodecylbenzene sulfonate has excellent surface task and also solid hydrophilicity, which can properly lower the tension of the oil-water interface and also accomplish emulsification. Consequently, sodium dodecylbenzene sulfonate is widely made use of in the formula of solutions such as cosmetics, printing and dyeing accessories, and pesticides.
Any type of item has its very own electrostatic fee, which can be unfavorable or positive. The build-up of electrostatic fees impacts and even hurts life or commercial manufacturing, as well as guides and removes the gathered hazardous charges to protect against production., Chemicals that cause inconvenience or damage to life are called antistatic agents. Sodium dodecylbenzene sulfonate can make materials, plastics, etc surface affinity for dampness, and also ionic surfactants additionally have a conductive impact, to make sure that fixed electrical power can leakage in time, thus lowering the threat and also hassle triggered by static electrical power.
In addition to the above-mentioned applications, in textile auxiliaries, it is often used as cotton material refining agent, desizing accessories, leveling representative in dyeing, and made use of as metal degreasing representative in steel electroplating procedure; made use of in paper industry Used as resin dispersant, really felt cleaning agent, deinking representative; made use of as passing through degreasing representative in natural leather market; used as anti-caking agent in plant food industry; utilized as air-entraining representative in concrete sector as well as numerous other elements or made use of alone or Make use of as a co-ingredient.
Degradation Method of Sodium Dodecylbenzenesulfonate in Water
Sodium dodecyl benzene sulfonate (SDBS) is a commonly used anionic surfactant, which has strong acid and alkali resistance, does not form precipitation with calcium, magnesium and other ions in water, and has efficient decontamination performance. At the same time, SDBS has excellent dispersing and antistatic properties, and is widely used in industry, agriculture and daily life. However, SDBS is extremely harmful, and it is difficult to degrade naturally in the natural environment when it is discharged into the water. It is easy to produce peculiar smell and a lot of foam in the water, which affects the oxygen exchange of the water body, accelerates the enrichment rate of the water body, and produces biological toxicity. SDBS entering the human body with drinking water can stimulate weight gain and accelerate the synthesis of cholesterol in the liver. Studies have found that SDBS has acute toxic effects on normal living organisms in water such as marine copepods. More studies have shown that linear sodium alkyl benzene sulfonate (LAS) can significantly increase the sperm aberration rate in mice.
Therefore, improving the water environment by promoting the degradation of SDBS in water by effective biological, physical or chemical methods is crucial to human health. At present, the degradation methods of SDBS mainly include physical adsorption method, ultrasonic method, microbial degradation method, catalytic oxidation method, foam separation method, precipitation method, membrane separation method, etc.
Physical adsorption refers to a method of adsorbing SDBS on the surface of solid adsorbents under intermolecular interactions. The more commonly used adsorbents are mainly diatomaceous earth, activated carbon, kaolin and so on.
As a method of removing organic pollutants, physical adsorption is simple and easy to operate. However, this method uses a large amount of raw materials, relatively high cost, cumbersome process treatment, and large energy consumption for regeneration, and it is difficult to reuse the adsorbent. The problem of secondary pollution has not been completely solved, which limits its wide application.
Ultrasonic method refers to a method in which macromolecular pollutants in solution are decomposed into small molecular substances by the action of ultrasonic waves under suitable acid-base conditions. This technology is used to degrade SDBS, which is of great significance for purifying the environment.
Generally speaking, ultrasonic method is a relatively simple method, and SDBS degradation rate generally increases with the increase of ultrasonic power. However, using ultrasound alone to completely degrade organic pollutants generally consumes a lot of energy and has a long reaction period. In foreign countries, ultrasonic degradation of organic matter is generally used as an effective auxiliary degradation method, and is not used alone.
Microbial degradation is a commonly used degradation method at home and abroad. Its main mechanism is: in the presence of microorganisms, the alkyl chain on SDBS undergoes oxidation or sulfonation reaction, and decomposes into small molecules, so as to achieve the purpose of degradation. The microbial degradation method generally does not cause secondary pollution. At present, the degradation rate of SDBS by microorganisms is mainly improved by screening the most effective degrading bacteria.
Catalytic oxidation is generally divided into chemical reagent oxidation, photocatalytic oxidation and electrocatalytic oxidation.
- Chemical reagent oxidation method
SDBS is generally degraded by the use of catalysts and oxidants. - Photocatalytic oxidation method
It is mainly to use light and catalysts to degrade SDBS. Photocatalytic oxidation is a method that has been studied more at present, mainly including photocatalytic oxidation of SDBS such as semiconductor materials and their composite materials, among which TiO2 and its composite materials are typical representatives. TiO2 photocatalytic oxidation surfactant has the advantages of non-toxicity, rapidity, wide application of substrates, complete mineralization, fixability, and no secondary pollution, and has attracted the attention of many researchers. - Electrocatalytic oxidation method
It is mainly a method to degrade SDBS directly or indirectly through chemical reactions on electrodes. At present, the electrocatalytic oxidation method mainly focuses on the research of micro-electrolysis method. This method is simple to operate and requires low equipment, but the energy consumption is relatively large, so the research on it is still very limited.
The removal of SDBS by foam separation method refers to passing air into the foam containing SDBS, adsorbing SDBS on the surface of the bubble, and separating SDBS after concentration. The foam separation method is simple to operate and has been industrialized at present. Compared with other methods, the removal rate of SDBS by foam separation method is relatively low, only about 50%.
The sedimentation method is also a relatively mature sewage treatment method in industry, which is mainly divided into flocculation sedimentation method and coagulation sedimentation method. Flocculation refers to the addition of flocculants to water, which generally includes processes such as destabilization of colloidal particles, formation of flocs, mutual adsorption, and sedimentation and separation. Coagulation refers to adding a coagulant to water, which generally includes processes such as colloidal dispersion, destabilization, and coagulation.
Membrane separation refers to a method in which certain components in a solution are separated by a selectively permeable membrane. Generally speaking, the membrane treatment method has a higher removal rate of SDBS, but the membrane is easily polluted, and it is difficult to be used for the second time.
