一、前言电感耦合等离子体(ICP)光谱分析是七十年代初引进我国的新技术,它具有检出限低、重现性好、基体影响小、能同时测定多种元素等优点,近年来已在冶金、地质、生物和环境保护等领域中得到了广泛的应用。岩石中钙、镁、铝、铁、锰、钛造岩元素的分析,目前通常是采用容量法、比色法等,这些方法准确度高、精密度好,但是测定速度慢,劳动强度大,成本高。本法引入ICP光源,用仪器分析代替繁琐的化学手工操作。样品经简单化学处理后,一次摄谱同时测
I. INTRODUCTION Inductively coupled plasma (ICP) spectroscopic analysis is a new technology introduced into China in the early 1970s. It has the advantages of low detection limit, good reproducibility, small matrix influence and simultaneous determination of various elements. In recent years Has been in metallurgy, geology, biology and environmental protection and other fields has been widely used. Rock, calcium, magnesium, aluminum, iron, manganese, titanium rock element analysis, the current capacity is usually used method, colorimetric method, these methods with high accuracy and precision, but the determination of slow, labor-intensive, high cost. This Law introduces ICP light source, using instrument analysis instead of cumbersome chemical manual operation. Samples after a simple chemical treatment, a simultaneous test spectrum
