本研究采用次氮基三乙酸作活化剂，锰催化高碘酸钾氧化考马斯亮蓝Ｇ２５０褪色的指示反应。该法选择性好，检出限达到６．７６×１０－８ｇ／Ｌ，２５ｍｌ工作液Ｍｎ（Ⅱ）含量线性范围在０．０２～０．３０μｇ。
In this study, using nitrilotriacetic acid as activator, manganese-catalyzed potassium iodate oxidized Coomassie Brilliant Blue G250 fading reaction. The method has good selectivity, the detection limit reached 6.76 × 10-8g / L, and the linear range of Mn (Ⅱ) content in 25ml working solution was 0.02-0.30μg.
