【摘要】 <正>关于铅的电流滴定已有很多报道,高鸿曾用铬酸盐进行了交流示波极谱滴定铅的研究,效果很好,但铬酸盐都有毒.近年来,不少文献报道了无氰络合滴定,但方法麻烦,同时锰干扰测定。1984年,高鸿提出利用氨羧络合剂自身的切口指示滴定终点,使示波极谱滴定法应用范围更加广泛,本文在此基础上,利用铅和EDTA在更多还原

【Abstract】 A satisfactory method for the determination of lead and manganese by osc-illopolarographic consecutive titmtion is described.Load and manganese are determined from l : 20 to 40 : 1 in their proportion.In addition to simplicity and rapidity, the method is accurate and the end point is distinct. A. lew of Fe3+, Al3+,Cu2+ and Zn2+donot interfere with the measurement of lead and manganese.更多还原
