摘要
甲基汞在生物样品中与巯基等紧密结合,需经适当的预处理才能将其解析后测定,样品前处理决定了整个方法的检出限、准确性等指标,是有机汞形态分析的关键步骤.在海产品中,汞以多种形态存在,如何将待测组分从样品中分离而不改变其形态,同时防止样品污染,减少目标物损失是汞形态分析中需要解决的重要问题,也是今后研究的重点.不同的分离检测仪器需要不一样的前处理,甚至是同样的分离检测仪器,因所分析的元素种类数量不同而有所差异.本文综述了近些年甲基汞检测所需要的前处理技术并进行了展望.
Abstract
Methylmercury is closely combined with sulfhydryl group in biological samples,and needs to be analyzed after appropriate pretreatment.The sample pretreatment determines the detection limit and accuracy of the whole method,mak-ing it a key step in the morphological analysis of organic mercury.In seafood,mercury exists in various forms.How to sep-arate the components to be tested from the sample without changing their morphology,prevent sample contamination and reduce the loss of target objects are an important problem to be solved in the analysis of mercury morphology,which is al-so the focus of future research.Different separation and detection instruments require different pre-treatments,and even the same separation and detection instrument varies depending on the number of elemental species being analyzed.This pa-per summarizes the pretreatment techniques required for methylmercury detection in recent years and provides an outlook.
