Abstract

In recent years, the increasingly severe environmental problems, especially those related to aquatic organisms and chemical pollution, have become a significant threat to the ecosystem and human health. Many new composite materials are used to control pollution because of their environmentally friendly properties. Hydroxyapatite is a kind of phosphate biomaterial. Compared with the original ore, it has improved the adsorption of heavy metals. Because of its eco-friendliness, good dispersibility, outstanding stability, and rich surface functional groups, it has a good prospect in treating water, air, and soil pollution. It is expected to inhibit toxic pollutants for a long time. Against this background, this paper introduces the adsorption of dyes and heavy metals by hydroxyapatite and its composites, and the influence of technological factors. For instance: contact solute concentration, time, temperature, pH of the solution, etc. on adsorption.
