| 摘 要： | 本文模拟广东地区酸雨的几种要素，分别对粤西云黄铁硫酸厂两种类型、两种粒径的废渣进行淋滤试验，考察废渣中的铊的释放规律，结果表明：粒径０．５－０．２５ｍｍ的炉底渣和沉灰渣分别在ＰＨ．１１和ＰＨ４．０２的硫酸介质中，铊的释放率最高。铊的释放率，滤出液的ＰＨ值与淋滤介质的ＰＨ值和离子强度密切相关。

| Abstract: | Based on some key elements of acid rain in Guangdong area, the slags of two types and two sizes are leached from sulphuric acid mill at Yunfu pyrite area, west-Guangdong, in order to observe the thallium leaching-out in the slags. The results indicate that more thallium is released from small size slags and dregs than those bigger ones under sulphuric acid medium of pH 2.11 and pH 4.02. The release rate of thallium and pH of leaching liquid are closely related with pH of medium and ionic strength. |
