| 摘 要： | 介绍了一种分析测定工业废渣中重金属的化学形态的方法：连续化学苹取法。测定结果表明，工业废渣中所含的重金属，有些形态属于不稳定结合态，有些则属于稳定结合态。水泥工业在处置利用工业废渣作水泥混合材时应尽可能地将其中的重金属由不稳定态转变为稳定态，以确保混合材水泥的安全使用。

| Abstract: | The sequential chemical extraction (SCE) method is used to study the chemical states of heavy metals in industry waste slag in this paper. The research results show that some states of heavy metals exist in stable forms and other states of heavy metals exist in unstable forms. It is suggested that chemical states of heavy metals should be converted from unstable to stable forms by some technical ways in order to use this blending cement safely when the industry slag is treated and utilized as cement admixture. |
