摘　　要：在制盐行业中,EDTA容量法被广泛应用于盐及盐化工产品中钙离子含量的测定。文章首先分析了不同标准中检出限的定义,随后根据检出限定义设计了钙离子检出限的测定方法,按照设计方法进行实验,统计数据得出结果,最后对钙离子检出限结果进行分析。设计实验从而测定EDTA容量法测钙离子含量的检出限,得出钙离子检出限为:MDL=0.002%。In salt industry,EDTA volumetric method are widely used to determine the Ca^(2+)content.This article firstly analyzed the definition of detection limits in different standards,and then designed a determination method of Ca^(2+)MDL according to the definition of detection limits.The experiment is carried out according to the design method,and the statistical data are obtained.Finally,the Detection limits of Ca^(2+)are analyzed.This article designed experiments to analysis the MDL of Ca^(2+)content.It is concluded that the MDL of EDTA volumetric method is:MDL=0.002%.
