| Abstract: | In the spectrophotometric measurement, it is important to consider the number of significannce digits in the process of sampling, pretreatment, solution preparation and dilution, regression equation, data calculation and other aspects, which has a significant impact on the accuracy of the analysis results. The maximum absorption wave length of scanning, solution dilution method and the calculation of the blank value of the instrument will have a profound impact on the analysis results. |
