摘要
利用价廉易得的PhIO-HBF4试剂,通过产生白色沉淀的方法方便地定性检测Cl-。同时,根据沉淀颜色与性质的不同,可区分Cl-,Br-,I-,S2-几种阴离子。氯离子的检出限为0.004 mol/L。
Qualitative detection of Cl - was implemented via formation of white precipitates, using cheap PhIO- HBF4as a detecting agent. Furthermore, four kinds of anions CI- , Br- , I - and S2- could be distinguished by color and properties of the precipitates. The detection limit of Cl- was 0. 004 mol/L. Non-metal ions especially heavy metal ions were involved in the method, which overcames drawbacks of conventional approaches.
