ICP-AES在检测不粘锅涂层中多种金属元素溶出量中的应用

Application of ICP- AES in Determination of Metals Dissolved Quantity in the Coating Layer of Nonstick Pan

本文根据电感耦合等离子体原子发射光谱(ICP-AES)的优势,建立了一种准确、快速、简便的同时测定不粘锅涂层中铅、镉、铬、砷溶出量的测定方法。不粘锅经过4%乙酸溶液的萃取,萃取液采用电感耦合等离子体原子发射光谱(ICP-AES)进行分析,经过大量试验确定了最佳工作条件。该方法操作简便、快速、准确,更好地满足了生产和实验室日常分析的要求。

In this paper, an accurate, rapid and convenient method was founded to detect the four metal dissolved quanti- ties in the coating layer of nonstick pan, according to the advantages of ICP-AES. The nonstick pan were extracted by 4% acetic acid. And then, tile extracted liquid was analyzed by ICP-AES. Through a series of experiments, the best working condition was determined. This method was accurate, simple and rapid, therefore it can better meet the requirements of the routine analysis for production process and laboratory.
