摘要


建立了一种微波消解-ICP-MS法测定磷石膏中的K,Na,Ca,Mg,As,Cd,Pb,Ni,Se,Cu,Cr,Mn,Co,Ag,Hg,Au等16种金属元素的方法.16种元素的校准曲线的相关系数在0.9990以上,检出限为0.0104~0.3399μg/L(n=11),加标回收率在91.5%~109.4%之间,相对标准偏差在0.50%~4.76%(n=5)范围内.表明该方法具有良好的准确度和精密度,适用于磷石膏中金属元素的测定. A method was established in phosphogypsum for the analysis of K,Na,Ca,Mg,As,Cd,Pb,Ni,Se,Cu,Cr,Mn,Co,Ag,Hg,Au by using ICP-MS.The correlation coefficients of the standard curves for these 16 elements were over0.9990.The detection limits were0.0104—0.3399μg/L(n=11),the recoveries were 91.5%—109.4%,and relative standard deviatian(n=5)were 0.50%—4.76% for 16 elements.This method has a good accuracy and precision for metal analysis in phosphogypsum.
