【摘要】 拟定了测定痕量锰的高灵敏方法，方法于基存在氨三乙酸作活化剂，以高碘酸钾催化氧化亮绿ＳＦ，锰的检出限３ × １０－１１ｇ，ｍｌ－１。测定面粉中锰获得满意结果。更多还原

【Abstract】 A high-sensitive method for determining the trace amounts of manganese has been developed. The method is based on the catalytic oxidation of light green SF by potassium periodate in the presence of nitrilo triacetic acid as an activ- ator. The detection 1:mit for manganese is 3 10- 11g m1- 1. The results are satis- factory for the determination of manganese in wheat flour.更多还原
