摘要
欧盟RoHS指令中有害物质包括:Pb、Hg、Cd、Cr6+、PBB和PBDE。而六价铬的检测方法主要有:针对聚合物材料和电子材料的USEPA3060A碱溶提取,采用USEPA7196A比色定量检测。上述方法不能很好地解决深色试样提取液颜色对比色的影响。本文采用固相萃取技术对样品进行处理,从而很好地克服了提取液颜色对比色影响的难题。
The hazardous substances in the EU ROHS containing：Pb. Hg. Cd. Cr^6＋. PBBS and PBDES. But the examination method of the chrome（Ⅵ） mainly has：The alkali of US EPA3060A that aims at the polymer materials and the electronics materials, Adopt the US EPA7196A compares the color fixed amount examination, But the above-mentioned method can＇t resolve the question that the deep sample extraction color interferes with comparison.This paper present solid phase extraction technique in sample treatment,It greatly overcome the difficulty.
