光电悬浮滴定(Heterometry)是由以色列化学家鲍伯泰尔斯基(M.Bobtelsky)发展起来的一种微量测定法。由于此法具有不少优点,近年来已为化学家们所注意,预计将有发展前途。本文就其基本原理、仪器装置和应用等方面作一简要的综述。一、基本原理利用沉淀反应可以测定很多元素的含量。当被测元素含量很低时,可用浊度分析法来进行分析。在浊度法中虽然沉淀反应的机构颇为简单,仪器亦仅需用 Heterometry is a micrometric method developed by the Israeli chemist Boboblsky. As this method has many advantages, it has been noted by chemists in recent years that it is expected to have a promising future. This article gives a brief overview of its basic principles, instrumentation and applications. First, the basic principle The precipitation reaction can be used to determine the content of many elements. When the measured element content is very low, turbidity analysis method can be used for analysis. Although turbidimetric precipitation reaction mechanism is quite simple, the instrument also only need to use
