摘　　要：根据加钙营养盐在磷酸介质中,加入EDTA使Ca^(2+)掩蔽,解决了加钙营养盐碘含量测定过程中结果偏低的问题,其精密度试验和回收率实验均令人满意。The EDTA was added to Calcification Micronutrient Salt for covering Ca2+ under the H3PO4 medium, it was solved that the iodine contents are low as determining the iodine contents in Calcification Micronutrient salt. The experimental results of recovery and accuracy are satisfactory using this method.
