PbSO4、PbO在柠檬酸钠溶液中溶解行为
Dissolution behavior of PbSO4 and PbO in sodium citrate solution
摘要
Abstract
Effects of dissolution time,dissolution temperature,the concentration of sodium citrate and the addition amount of citric acid on dissolution behaviors of PbSO4 and PbO in sodium citrate solution were investigated. The results showed that PbO dissolution rate reached 5 1 . 1 6% after dissolving for 0.5 h,and with the increase of dissolution time,PbSO4 dissolution rate first increased and then decreased. PbSO4 dissolution rate increased and PbO dissolution rate decreased 37.98% with the increase of dissolution temperature,however,both of them increased when increasing the concentration of citric sodium. With the increase of citric acid addition,PbSO4 dissolution rate decreased to 6 . 3 9%, by contrast,PbO dissolution rate obviously increased,reached 9 7 . 3 2%. The results have provided basic data and theoretical support for new technology of recovering lead from used lead-acid battery with citric acid-sodium citrate solution.关键词
