摘要
探讨锰（Ⅱ）与依来铬青R（SCR）、邻菲罗啉（Phen）、溴化十六烷基吡啶（CPB）四元显色体系的最佳条件。在pH8．5～10的氨性条件下，该蓝紫色络合物在590nm处有最大吸收：络合物组成为Mn（Ⅱ）：SCR：Phen：CPB=1：1：1：2；Mn（Ⅱ）浓度在5～40ug／25mL范围内符合比耳定律。方法用于钢样中微量锰的测定，结果准确。
Introduced in the essay is the best condition for the comlpex compound between Mn(II) and SCR, Phen, CPB. withammoniation of pH8. 5-10,the violet-blue complex has the maximum consumption peak at 590nm,having a composition of Mn(II): SCR: Phen: CPB=1: l: l: 2. The dead Of Mn(II) within the range of 5-40ug/25ml complies to the Beer Lew.This amalysis applies to that of the micro-Mn in the steel sample,Which possesse a precise result.
