目前测定氟的方法有重量法,酶催法,滴定法,比色法和电位法等多种方法。而常用的是滴定法、比色法和电位法。这些方法都存在干扰因素多、样品处理手续繁琐、需要作图计算等缺点。蚕桑生产在受氟素污染的地区和季节,需要在短时间内分析大量的桑叶样品含氟量,以便进行监测、预报和采 The current determination of fluoride methods are gravimetric method, enzymatic method, titration, colorimetric and potential methods and other methods. Commonly used titration, colorimetric and potential method. These methods have many interference factors, sample processing procedures cumbersome, need to calculate the shortcomings. Silkworm mulberry production in areas and seasons of fluorine contamination, the need to analyze a large number of mulberry leaf samples in a short time the amount of fluorine in order to monitor, forecast and mining
