    从高铅玻璃中回收氧化铅的试验研究

    Experimental study on recycle of lead from the high-lead glass

    • 摘要: 我国铅资源逐渐匮乏,如何从玻璃粉等废品中高效回收铅日益受到重视。研究采用浸出-置换的方法对高铅玻璃粉进行处理,考察了浸出温度等因素对浸出效果的影响。结果表明:在氢氧化钠浓度为5mol / L,浸出液固比为4:1,浸出温度为95℃,浸出时间为2h的最佳条件下,可获得铅浸出率为84.32%的指标,采用分批添加锌粉的方式,可使浸出液中铅的置换率达到99.28%。研究对缓解国内铅原料的供应有重要意义。

       

      Abstract: How to efficiently recycle lead from glass powder and other waste was gotten more and more attention because the Lead resources were increasingly scarce in China. Leaching-replacement method was used for processing high-lead glass powder and the effects of experimental conditions were investigated, such as leaching temperature. The leaching rate of 84.32% lead was obtained under the condition of the concentration of sodium hydroxide of 5mol/L, leaching of liquid-solid ratio of 4:1, leaching temperature of 95?C, and leaching time of 2h. Under the above experimental conditions, lead leaching solution of 99.28% was obtained bySbatchSadditionSof zinc. The research had important significance to alleviate the domestic supply of lead.
