1964年Ingamells最早报导了偏硼酸锂是一个很好的助熔剂,同时将其成功地应用于硅酸盐分析。经过近20年的发展,目前已被公认为岩矿分析中一种先进的熔样方法。它熔样完全、简单、快速,所获溶液适用于多种测定方法,并可测定多种元素,最多可达17种。但是,采用该熔剂熔样,存在着熔球难于提取和硅酸容易聚合等问题,致使该熔样方法在国内尚未得到广泛应用。本文主要阐述快速提取熔融物的最佳条件,防止硅酸聚合的方法,以及在采用原子吸收法测定岩石中9个常量组份时,元素间的干扰情况,提出了一个快速岩石全分析方法。
In 1964, Ingamells first reported that lithium metaborate is a good flux and has been successfully applied to silicate analysis. After nearly 20 years of development, has now been recognized as an advanced rock melting analysis method. It is a complete melting sample, simple and fast, the solution obtained for a variety of determination methods, and the determination of a variety of elements, up to 17 species. However, with this flux melting sample, there are some problems such as difficult to extract the molten ball and easy polymerization of silicic acid, which makes the melting sample method not yet widely used in China. This article describes the best conditions for rapid extraction of the melt to prevent the polymerization of silicic acid, as well as the use of atomic absorption spectrophotometric determination of nine constitutive components of the interference between elements, a rapid total analysis of rock method.
