| Abstract: | Objective To evaluate the method of As-Ce catalysis spectrophotometry for detection of urine iodine. Method The method of water quality analysis was used to evaluate the precision and accuracy of spectrophotometry. Results The total standard deviation of variety of solution was less than 5% of the concentration. The precision agreed with the requirement, and the creditability of the averaged recovery was in the range of permission (R/d = 0.954). Conclusions The error of determination in the laboratory can be controlled in a limited range of regulation, and the result can be of certain accuracy. |
