摘要
采用电感耦合等离子体质谱法(ICP-MS)测定,超级微波消解并优化不同类型肥料的消解条件,建立了超级微波-ICP-MS测定多种类型肥料中V、Cr、Co、Ni、As、Cd、Hg、Tl、Pb 9 种污染元素含量的方法.本方法的线性相关系数均大于 0.9999,方法检出限范围为 0.000500～0.0293 mg/kg,各元素加标回收率为85.0%～110%,该方法灵敏度高、准确度较好,可实现不同类型肥料样品中多元素的准确测定.
Abstract
A method for the determination of nine pollutant elements,namely V,Cr,Co,Ni,As,Cd,Hg,Tl and Pb in various types of fertilizers was established by using inductively coupled plasma mass spectrometry(ICP-MS),super microwave digestion and optimization of the digestion conditions for different types of fertilizers.The linear correlation coefficients of this method were all greater than 0.9999,and the limits of detection of the method were in the range of 0.000500-0.0293 mg/kg.The recoveries of the spiked elements were 85.0%-110%,and the method is sensitive and accurate,which can realize the accurate determination of the multiple elements in different types of fertilizer samples.
