ICP光谱法测定硅酸盐岩石中27个元素——介绍硫载体缓冲剂

Determination of 27 Elements in Silicates by ICP Spectrometry——Introduction of Sulphur Carrier-buffer

本文采用硫载体缓冲剂,使ICP粉末射流进样方法[1]得到提高。一次取样、单取摄谱测定元素增加到钡、铍、硼、铅、钛、锰、钒、铬、铌、镧、锆、银、镱、钇、钪、钴、锶、镍、铊、铟、镓、锡、钽、钍、铈、钼等27个元素。 测定灵敏度普遍提高2—20倍。

A sensitive analysis for determination of 27 elements by ICP-AES powder method is studied. Sulphur is used as carrier in the buffer. The sensitivity of this method is generally increased in 2-20 fold. The detection limits and the range of determination for 27 elements are reported.
