共沉淀浮选分离富集铊

Separation and Preconcentration of Thallium by Coprecipitation and Floatation Process

本文首次采用氢氧化铁做共沉淀剂,阴离子表面活性剂油酸钠作起泡剂,共沉淀浮选富集水样中铊,实验结果表明,其富集率可达96±2.5％,方法具有设备简单,速度快等优点,有实际应用价值。

This paper firstly reports that thallium can be coprecipitated from water system by coprecipitation and Chemical floatation method using ferric hydroxide as coprecipitant and anion surfactant Sodium oleate as bubble agent.The expiemental results indicate that the enriching ratio of thallium is 96 ± 2.5% and the method is practical for having speedy effet by Silmple equipment
