利用磷酸镁水泥对Pb2＋、Zn2＋、Cu2＋重金属硝酸盐进行固化,研究其浸出率变化规律,并对不同种类重金属对磷酸镁水泥水化产物种类、形貌及其微区元素进行了探讨.研究表明,磷酸镁水泥对重金属进行固化效果Pb2＋＞Cu2＋＞Zn2＋,浸出毒性数值远低于国家标准要求.Pb2＋促进了水化产物的生成,Cu2＋和Zn2＋抑制水化.采用 EDS 能谱分别检测水化产物中Pb、Zn和Cu,分析磷酸镁水泥对重金属硝酸盐稳定/固化效果.

The leaching rate of magnesium phosphate cement with Pb2+,Zn2+,Cu2+ were studied.The kind, morphology and micro area elements of hydration products of magnesium phosphate cement added heavy met-als,were discussed in this paper.Research shows that:the magnesium phosphate cement on heavy metal solidi-fication effect of Pb2+>Cu2+> Zn2+,while the value of leaching toxicity was far lower than the national stand-ard requirements.Pb2+ could promote the formation of hydration products,while Cu2+ and Zn2+ were opposite. Pb,Cu and Zn were respectively detected used the EDS spectrum detection,which was proved that it cans or not stabilization/solidification of heavy metals in the hydration products of magnesium phosphate cement.
