摘要
应用分级提取法考察了黄铁矿及烧渣中铊的赋存形态,包括酸可交换态、易还原态、可氧化态和残余态中铊的浓度,据此讨论了黄铁矿及烧渣中铊的形态分布,认为黄铁矿及烧渣中铊的释放均不容忽视.
Sequential chemical extraction was employed to investigate the states of Thallium in pyrite and cinder, including exchangeable, reducible, oxidable, and residual states. On the basis of these, we discussed the state distribution of Thallium in pyrite and cinder, and suggested that the Thallium release from pyrite and cinder should be paid attention to.
