| 摘 要： | 通过对废酸中各主要成分的分析,对氟离子选择电极法测定氟化物的原理的剖析,最终选择先调节待测溶液的酸碱度去除干扰后,再进行氟化物含量的测定。使用国标所描述去干扰的方法进行验证,最终得出两种方法所测得的氟化物含量结果一致。通过回标回收实验,确定测定结果的准确度也达到国标要求。

| Abstract: | Through the analysis of the main components in waste acid,the analysis of the principle of fluoride determination by fluoride ion selective electrode method,the final choice is to adjust the pH of the solution to be tested to remove interference,and then determine the fluoride content.The method described in the national standard is used for verification,and the results of fluoride content measured by the two methods are consistent.Through the recovery experiment,the accuracy of the determination results also meet the requirements of the national standard. |
