以氨三乙酸存在下锰 催化高碘酸钾氧化孔雀绿的反应作指示反应 ,用孔雀绿选择性电极作指示电极 ,对于用催化电位滴定法测定微量锰进行了研究 ,选择了适宜的实验条件 ,并测定了中草药中的锰的含量 ,所得结果与原子吸收法一致。
In the presence of nitrilotriacetic acid, the reaction of malachite green with potassium periodate was indicated as the indicator reaction. The malachite green selective electrode was used as the indicator electrode. The determination of trace manganese by catalytic potentiometric titration was studied. The suitable experimental conditions , And the content of manganese in Chinese herbal medicine was measured. The results obtained are consistent with the atomic absorption method.
