Application:

Examples of its applications are as follows:

1) Determination of aluminum content in food by aluminum reagent spectrophotometry. After the sample is digested (the water sample can be directly sampled and measured), it is neutralized with sodium hydroxide solution, and then the color is developed by aluminum reagent, and the absorbance value is measured at 520nm, and the content is measured by the standard curve method. The iron in the sample interferes with the determination and can be shielded by ascorbic acid and hydroxylamine hydrochloride. The linear range of this method is 2μg/25mL20μg/25mL, the recovery rate is 96.8%101%, and the relative standard deviation is 1.27%. This method has the advantages of simple operation and accurate results. The analysis of aluminum content in food is of great significance.

2) Determination of trace aluminum oxide in aluminum ingot by aluminum reagent spectrophotometry. The AlBr3 produced by the reaction between metal aluminum and liquid bromine is soluble in methanol, but Al2O3 does not react with liquid bromine under anhydrous conditions. The separation of Al and Al2O3 is realized. The aluminum reagent photometric method is used to determine aluminum ingots. In the trace Al2O3. The results show that in the NaAc-HCl buffer solution at pH 4.4, the complex formed by aluminum and aluminum reagent has a maximum absorption at 530 nm. The content of Al2O3 in the range of 0~3.0mg/L follows Beer’s law. The detection limit of the method is 0.005mg/L. The established method is used for the determination of Al2O3 in actual aluminum ingot samples. The precision (RSD, n=5) is 3.50%~14.3%, and the recovery rate of standard addition is 98.9%~99.7%.

3) Determination of total aluminum in soil by aluminum reagent colorimetry. For the determination of total aluminum in soil, the subtraction method or EDTA volumetric method is mostly used in China. These methods are easy to use, but the reagent consumption is large and the operation is more troublesome. The colorimetric determination of total aluminum in soil with aluminum reagent, LM Jackson has been as early as the 1950s Recommended. But Jackson believes that due to the large number of interfering ions in this method, aluminum must be separated from other interfering ions before the determination. In the past 20 years, foreign analysts have done more research on the determination of aluminum with aluminum reagents. PHHsu recommends using it. Acidify the tested solution to prevent the interference of phosphate ions and silicate ions. TCZJayman et al. used ascorbic acid to eliminate the interference of Fe3+. References recommend the use of aluminum reagent colorimetric method to determine the total aluminum in the soil sodium carbonate molten solution and hydrofluoric acid digestion solution.

4) Cation exchange resin separation-aluminum reagent spectrophotometric method to determine the form of aluminum in soil. Some experiments have studied the optimal conditions for the determination of aluminum in the soil solution by the aluminum reagent spectrophotometry, focusing on the influence of coexisting ions, especially inorganic ions and organic anions in the soil solution on the determination of aluminum. Using cation exchange resin to separate, established a method to determine the form of aluminum in soil solution and natural water. This method can be used to determine total reactive aluminum, total mononuclear aluminum and stable mononuclear aluminum. The acid-soluble aluminum is obtained by subtracting the total mononuclear aluminum from the total reactive aluminum. Unstable mononuclear aluminum is obtained by subtracting stable mononuclear aluminum from total mononuclear aluminum. It was compared with the cation resin exchange separation catechol violet spectrophotometric method. The results show that the catechol violet spectrophotometric method is more sensitive, but the interference of iron is greater. The sensitivity of the aluminum reagent photometric method is slightly lower, but the interference of iron is less. Cationic resin exchange separation of aluminum reagent spectrophotometry is more suitable for determining the form of aluminum in soil solutions with relatively high iron content.

5) Study on the determination of aluminum content in tea garden soil and tea plant by aluminum reagent spectrophotometry. The soil of tea gardens in my country is mostly acid brick red soil or red soil, which is rich in aluminum, including a certain amount of soluble aluminum, manganese, and iron, which increases with the decrease of pH. Soluble aluminum is prone to aluminum damage to general crops, causing it to be deficient in phosphorus, which is one of the causes of acid damage. Tea plant is a typical aluminum-loving crop, which can accumulate a large amount of aluminum in its body, which is called poly-aluminum crop. To study the nutritional and physiological effects of aluminum on tea plants, it is necessary to investigate the dynamics of the soluble aluminum in the soil of the tea garden and the distribution of aluminum in the body of the tea tree. Since aluminum is in a trivalent state in the solution, it can form a stable red complex with aluminum reagent (rose red tricarboxylic acid) in an acidic medium, which can be colorimetrically determined. Therefore, the aluminum reagent spectrophotometry is not only a simple method to determine aluminum, but also has high sensitivity.
