文献报导利用锰(Ⅲ)氧化氯离子的催化反应以测定0.005～0.04微克/毫升的钯。我们利用这个反应,并参考文献,拟出测定0.005～0.05微克钯的反应条件,并对反应机理、干扰元素、分离手段、样品分析作了工作。钯(Ⅲ)对锰(Ⅲ)氧化氯离子之间的反应具有催化效应。催化反应速度随钯的浓度而改变。降低溶液的酸度,反应终止。当催化反应进行一定时间后,用水 The literature reports the use of manganese (III) chloride oxidation of the catalytic reaction to determine 0.005 ~ 0.04 micrograms / ml of palladium. We use this reaction, and reference literature, to develop the determination of 0.005 ~ 0.05 micrograms of palladium reaction conditions, and the reaction mechanism, interference elements, separation methods, sample analysis made a work. Palladium (III) has a catalytic effect on the reaction between manganese (III) chloride ions. The catalytic reaction rate varies with the concentration of palladium. Reduce the acidity of the solution, the reaction is terminated. When the catalytic reaction for a certain period of time, water
