In order to supervise the iodine contents in salt on market and in household, a nationwide survey supported by ILSI was conducted. 91 salt samples on market and 531 samples in household were respectively collected from 35 manufactures in 11 selected provinces and from 165 districts in 25 provinces. The analytical method of determining the iodine in salt was based on Ce As I catalytic reaction. It was found that the iodine contents of the examined samples varied considerably and ranged from 3 0 to 100 3 mg/kg...

In order to supervise the iodine contents in salt on market and in household, a nationwide survey supported by ILSI was conducted. 91 salt samples on market and 531 samples in household were respectively collected from 35 manufactures in 11 selected provinces and from 165 districts in 25 provinces. The analytical method of determining the iodine in salt was based on Ce As I catalytic reaction. It was found that the iodine contents of the examined samples varied considerably and ranged from 3 0 to 100 3 mg/kg salt for market samples and 0 0 to 90 0 mg/kg for households samples. 71 4% and 73 4% samples reached the national standards respectively. 9 9% of market samples and 13 4% of the total 531 samples from households were lower than the national standard, while 18 7% and 13 2% of samples was higher. The percentage of coarse salt with low/no iodine content was 57 1%.

为了更好地监测和控制市售食盐和居民用盐中碘的质量,在ILSI的支持下,对全国11个省市自治区的35个盐厂、盐库、盐业公司出品的91份市售食盐和全国25个省市自治区165个城乡的531个居民户食用盐进行了抽样检测,食盐碘含量测定选用砷铈接触法。调查结果发现市售食盐和居民户食盐碘含量分别分布在3.0~100.3mg/kg,0.0~90.0mg/kg,合格率分别为71.4%和73.4%。9.9%市售食盐和13.4%的居民食用盐碘含量低于国家标准,另有18.7%的市售食盐和13.2%的居民户食盐碘含量过高。粗盐中低碘/无碘食盐的比例为57.1%。

Based on the comparison between sodium hypochlorite oxidation method of GB/T13025.7-1999and saturated bromine water oxidation method of GB/T13025.7-91in iodine content testing of iodized salt,saturated bromine water oxidation method of GB/T13025.7-91is recommended as the arbitration of testing io-dine content in iodized salt.

根据对GB/T13025.7-1999次氯酸钠氧化法和GB/T13025.7-91饱和溴水氧化法测定碘盐碘含量方法的比对,建议用GB/T13025.7-91饱和溴水氧化法作为测定碘盐碘含量的仲裁法。
