铅酸蓄电池极板中活性物质含量的测定

摘要

Using the iodimetry method and complexometric titration method,the contents of active substances,which are PbO2 in positive plate and PbO？in negative plate were determined respectively.The results were used to judge the battery＇s quality.The method is simple and easy to judge the terminal point.%采用碘量法和配位滴定法分别测定铅酸蓄电池正、负极板中活性物质PbO2、PbO的含量,借此判断电池是否合格。此方法步骤简单,易于判断终点。
