摘要
本文研究了在 NH3 · H2 O- NH4Cl介质中锰催化过氧化氢氧化苋菜红的褪色反应及其动力学条件 ,建立了测定痕量锰的新方法。该方法的检出限为 5 .6× 1 0 -4μg/m L Mn,线性范围为 0～ 1 .8μg/2 5 m L Mn,用于测定井水中痕量 Mn。
The decolourisation of amaranth by oxidation of hydrogen peroxide in ammonium muriate medium using manganese as catalyst is investigated. A new method for the determination of Mn has been developed. The limit of detection of Mn is 5.6×10\+\{-10\}g/ml, the linear range is 0～1.8μg/25ml. The method has been used to determine trace Mn in water .\;
