氢化物发生HG-ICP-AES测定动物源性水产品中的无机砷含量

Determination of Abio-Arsenic Residues in Animal Origin Aquatic Products by HG-ICP-AES Method

建立了氢化物发生电感耦合等离子发射光谱(HG-ICP-AES)测定动物源性水产品中无机砷含量的方法,并对ICP-AES工作参数及氢化物发生条件进行了优化和选择。方法的检出限为0.92μg.L-1,线性范围为0~100μg.L-1,相对标准偏差为1.24%;回收率范围为98.5%~101.6%。本法适用于低含量无机砷含量的日常检测测定。

A method for the determination of abio-arsenic residues in animal origin aquatic products by HG-ICP-AES method was developed.Operation parameters of ICP-AES and condition of hydride generation were optimized and selected.The detection limit is 0.92 μg·L^(-1).The RSD is 1.24%.The recovery is in the range of 98.5%～101.6%.This method is used to determine abio-arsenic residues in products of animal origin seafood with satisfactory results.
