摘要
用硫酸铈接触法对哈尔滨市动力区（１９９２年）和呼兰县（１９９３年）的居民末稍碘盐和碘盐加工点销售点碘盐共２３２份盐样进行了测定分析，其结果：动力区居民末稍盐ｎ＝７６，ｘ±ＳＤ＝１９．５８±１２．８６；碘盐销售点，ｎ＝７７，ｘ±ＳＤ＝２０．５９９±２０．１７４．呼兰县居民末稍盐ｎ＝７５，ｘ±ＳＤ＝８．８９±５．９１；加工点ｎ＝１９，ｘ±ＳＤ＝４６．０８±３８．９３；销售点，ｎ＝４，ｘ±ＳＤ＝２０．７５±１７．７０．平均回收率为９８％．
In this paper, 232 samples of resident no-sell salt sites and KIO3-salt sell sites were analysed with Ce (SO4) 2 way in Donli district and Hulan county. Following results: resident nosell salt sites in Dough district n=76, x±SD= 19. 58±12. 86; KIO3-salt sell sites n = 77. x±SD= 20. 599± 20. 174; resident no-sell salt sites in Hulan county n = 75. x ±SD= 8. 89±5. 91; KIO3 -salt sell sites n =4. x ±SD= 20. 75±17. 70; process sites n = 19, x±SD= 46. 08±38. 93; recovery rate is 98%.
