摘要： 溴邻苯三酚红(BPR)曾用作Mg3+的螯合滴定指示剂。我们系统研究了碱土金属离了-BPR-表面活性剂显色体系,发现在pH 9.2的氨缓冲介质中,Mg2+-BPR-溴化十六烷基吡啶(CPB)体系具有理论和实用价值。

Abstract: The new colour reaction of Mg-bromopyrogallol red (BPR)-cetylpyridinium bromide (CPB) system has been examined. The mechanism of increasing sensitivity has been discussed. Some samples have been analysed.
