微量溴与碘离子的连续测定

Continuation Determination of Micro-amouts of Bromide and Iodine

本文讨论了溴与碘离子分别进行倍增反应的条件，并以碘量祛对还原产生的碘单质进行滴定。据此，实现了在大量氯离子存在下微量溴与碘的连续测定。结果可靠，方法简便。RSD：Br－2．0％I-1．5％回收率；Br－99％～101％I-99％～101％

In this paper. The condition of bromide and iodine redouble reaction is reperted, be reduced toiodine be titrated with iedometric method, so a method of continuation determination of micro-amouts of iodineand bromide with a large amout chlorde ion has ben developed. The test showed that result is reliable. The rel-ative standard deviation were Br- 2. 0%, I- 1. 5 %. The recoveries were 99~101 %.
