摘　　要：研究了在NH3-NH4Cl介质中,Mn2+催化H2O2氧化偶氮胭脂红的褪色反应的反应条件,建立了测定痕量锰的新方法.该方法的线形范围为0～80μg/LMn2+,检出限为0 6μg/L.用该方法测定水样中锰的含量,获得满意结果.The decolouring condition of Ponceau oxidized by H_2O_2 in NH_3-NH_4Cl medium using Mn^(2+) as catalyst was investagated. A new method of trace manganese determination was established. The linear range is 0～80μg/L and the limit of detection is 0.6μg/L . The method was used to determine the trace manganese in water and the results were satisfactory.
