摘要
介绍用铅盐反滴EDTA滴定法测定镀锡钢带的镀锡量。该法回收率为 99.2 %～ 99.8% ,实物测试相对标准偏差为 0 .35 %～ 1 .36 % ,可以满足科研和产品质量检验要求。本法适用于电镀锡钢带镀锡量的测定 。
To introduce the determination of Sn coat on Sn plated steel strip using EDTA titration with lead salt back dropping.The recovery ratio of Sn is up to 99.2%～99.8% with the method.The relative standard deviation of practical test is 0.35%～1.36%,which can meet the needs of science research and product quality examination.The method is suit for the determination of Sn coat on Sn electroplating steel strip,the Sn plating steel strip and steel wire by dipping can be also tested with it as reference.
