Preparation method of copper slag-based phosphate cementing material
The invention belongs to the field of adsorption materials, and relates to solidification/stabilization repair of heavy metal polluted water, in particular to a preparation method of a copper slag-based phosphate cementing material for heavy metal adsorption, and calcium oxide is added as a modifier in the preparation process of the cementing material. In the process of preparing the copper slag-based phosphate, CaO is added as a modifier to promote the combination of the copper slag and the phosphate and improve the utilization rate of Fe ions, so that the heavy metal adsorption and solidification capability of the copper slag-based phosphate cementing material is enhanced.
本发明属于吸附材料领域，涉及重金属污染水体的固化/稳定化修复，具体涉及一种用于重金属吸附的铜渣基磷酸盐胶凝材料的制备方法，所述胶凝材料制备过程中加入氧化钙作为改性剂。本发明在制作铜渣基磷酸盐过程中，加入CaO作为改性剂，以促进铜渣与磷酸盐的结合，提高Fe离子的利用率，从而增强铜渣基磷酸盐胶凝材料吸附固化重金属的能力。
