摘要
研究了用氨三乙酸（NTA）作活化剂，锰催化高碘酸钾氧化维多利亚蓝B褪色的指示反应。该法选择性好，灵敏度达到1．49×10（－10）g／ml，线性范围为0．10－0．35μg／25ml。用于粮食中痕量锰的测定，结果令人满意。
A new indicator reaction is developed on the basis of manganese catalyzed oxidation Of victoria blue B by potassium periodate with nitrilotriacetic acid as an activator. The method has good selectivity, its sensitivity is 1. 49×10(-10) g/ml, and the linear range is 0. 01 ~ 0. 35μg/25ml. The method has been applied to the determination of manganese in foods with satisfactory results
