摘要
研究了淋滤时间、淋滤液pH值、粒径及滤速对沉灰渣中铊释放的影响 ,结果表明 :上述因素均能影响废渣表面铁氧化物的水解 ,这种水解支配着铊释放的过程 ;滤速及碱性颗粒的参予能显著影响废渣表面的水解作用 .
The influence to release of thallium from slag on time of leaching,pH of leaching liquid,size of slag and speeds of leaching are inspected.The results indicated that these factors can all influe- nce hydrolysis of chloride of iron in slag surface.The hydrolysis arranged the release of thallium.Speed of leaching and addition of alkali pellet influenced obviously hydrolysis of chloride of iron.
