在地球化学探矿中,氟、氯等卤族元素已成为重要找矿指示元素。但至今尚缺简单、快速、准确、灵敏度高的方法来分析岩石、土壤中的氟、氯。寻求新的方法必须有以下特点:(1)矿样中所含氟、氯应分解完全并有效地消除对电极法测定氟、氯的干扰因素;(2)响应快,结果准确,灵敏度高;(3)尽量不用贵重试剂以利节约。
In geochemical prospecting, halogens such as fluorine and chlorine have become important indicator elements for prospecting. However, there is still no easy, fast, accurate and sensitive method for analyzing fluorine and chlorine in rock and soil. The new method must have the following characteristics: (1) The fluoride and chlorine contained in the ore sample should be decomposed completely and effectively to eliminate the interference factors of determination of fluorine and chlorine by the electrode method; (2) The response is fast, the result is accurate and the sensitivity is high; (3) Try not to use expensive reagents to save.
