摘要：Nano-hydroxyapatite prepared by homogeneous precipitation using calcium nitrate and diammonium phosphate as raw materials has a good effect on removing heavy metal ions in water, and its reaction mechanism belongs to an adsorption action. The adsorption capacity of heavy metal ions on nano-hydroxyapatite modified by modifier was greatly improved. At present, the laboratory has been able to successfully synthesize nano hydroxyapatite and modify its surface with modifier.In this paper, the surface modification of nano hydroxyapatite using different modifiers was briefly introduced, and the effect of modified nano hydroxyapatite on removing Cu²⁺ in water was studied. Based on the results of the data, we find out the modifier with the highest removal rate of Cu²⁺, which is used to guide the applications of the future in industry.
