用苯萃取碘—碘化物—孔雀绿络合物分光光度法测定微量BrO_3^-

THE SPECTROPHOTOMETRIC DETERMINATION OF TRACE BrO_3^- BY EXTRACTING Tile IODIDE—IODINE—MALACHITE GREEN COMPLEX WITH BENZENE

本文研究了BrO_3^-与I^-反应生成I_2的条件和所生成的碘与碘化物及孔雀绿形成有色络合物光度测定微量BrO_3^-的方法。本法有灵敏度高、简便快速、精密度及准确性好等优点。

In this paper the conditions are studied for the formation of I_2 in the reaction of BrO_3^- with I^-, and the spectrophotometric determination of trace Bro_3^- by iodide-iodine-malachite green complex. This method offcrs the advantages of high sensitivity, rapid and simple operation, good reproducib lity and accuracy.
