The common visual colorimetry is a standard series method, that is, different amounts of standard solutions of an object to be measured are put into a group of identical colorimetric tubes, and color development is carried out according to the analysis steps to prepare a standard color gradation with gradually changing color. The sample solution is developed under the same condition, and compared with the standard color gradation, the standard with the most similar color is visually found out, and the content of the component to be measured in the sample is calculated and determined according to the amount of the standard solution contained in the standard solution. The photoelectric colorimetry measures the absorbance of a series of standard solutions on a photoelectric colorimeter or a similar structure, plots the absorbance to the concentration, draws a working curve, and then finds the concentration or the content of the solution of the component to be measured on the working curve according to the absorbance of the solution of the component to be measured.
