引言 ICP—原子发射光谱法(AES)具有灵敏度高、精确度好、基体效应小、选择性高、标准曲线线性范围宽等优点,近年来被广泛应用于各种样品如土壤、食品,生物样品等常量和微量元素测定,而把它用于硅酸盐全分析,在国内还没有得到开发。硅酸盐分析通常采用化学法,分光法,这些方法周期长、操作繁琐、微量元素测定误差大,对于一些组成复杂的制品如含有锆、铪、锡等测定困难,采用ICP—AES法可以分析硅酸盐制品耳的Si、Al、Fe、Ti、Ca、Mg、B、Zr、Hf、K、Na等元素,相对误差在±3％之内。
INTRODUCTION ICP-AAS has the advantages of high sensitivity, good accuracy, small matrix effect, high selectivity and wide linear range of standard curve. It has been widely used in various samples such as soil, food, biological samples Other constant and trace elements determination, and its use for silicate full analysis, in the country has not been developed. Silicate analysis usually adopts chemical method and spectrophotometry. These methods have long cycle, cumbersome operation and large measurement error of trace elements. The determination of complex components such as zirconium, hafnium and tin can be analyzed by ICP-AES Silicate products ear Si, Al, Fe, Ti, Ca, Mg, B, Zr, Hf, K, Na and other elements, the relative error within ± 3%.
