| Abstract: | [Objective]To conduct the quality control of ammonium persulfate-arsenic cerium catalysis spectrophotometry for determination of urine iodine. [Methods]WS/T 107-2006 was adopted to evaluate the accuracy and precision of the method. [Results]Within the range of the standard curve,there was a good linear relationship between the iodine concentration and the logarithm of absorbency,r>0.999.The relative standard deviation(RSD)was less than 10%,and the variation coefficient was less than 10%. [Conclusion]The acc... |
