水产品中镉的初步形态分析及无机镉方法学研究

摘要

The two forms of total cadmium and inorganic cadmium in aquatic products were ana-lyzed, and a method for determination inorganic cadmium in aquatic products was established .The distri-bution of total cadmium and inorganic cadmium in aquatic products were compared .The inorganic cadmi-um methodology study showed that the method linear , detection limit, precision and accuracy were good . It was suitable for the determination of inorganic cadmium in aquatic products .%对水产品中总镉和无机镉两种形态进行分析，建立水产品中无机镉的测定方法，对比总镉和无机镉在水产品中分布。无机镉的方法学研究表明该方法线性、检出限、精密度、准确度均良好，适用于水产品中无机镉的测定。
