【摘要】 对 176 2份碘盐进行了快速定量检测筛查 ,并与实验室方法对照 ,检测结果为 :①销售点碘盐含碘量M为 4 0 5× 10 - 6 ,合格率为 97 4 % ;非碘盐及碘盐含碘量M <2 0× 10 - 6 ,均为“0” ;>6 0× 10 - 6 为 2 6 %。②居民食盐含碘量M为 4 0 0× 10 - 6 ,合格率为 95% ;<2 0× 10 - 6 为2 5% ,>6 0× 10 - 6 为 0 7% ;非碘盐为 1 8%。本法与实验室定量方法比较 ,P >0 0 5,无显著差异。判定本法是准确的。更多还原

【Abstract】 iodate samples were analysed by rapid quantitative sieving.The results show that (a) M is 40 6 at the retailers,where 97 4% are qualified;both non-iodate and content less than 20×10 -6 are zero percent,and content greater than 60×10 -6 is 2 6%;(b) M is 40×10 -6 at the reoidentiall Consumers,where 95% are qualified,while content less than 20×10 -6 is 2 5%,greater than 60×10 -6 is 0 7%,and non iodate is 1 8%,no significant difference compared with the laboratory result, P >0 05. This shows the method of quantitative sieving analysis is reliable.更多还原
