Apatite-Based Materials for Heavy Metal Removal
Year: 2026
Type: article
Abstract: The increasing prevalence of heavy metals in industrial effluents is a point of great interest due to their toxicity, persistence, and bioaccumulation. Among all treatment methods, adsorption is noteworthy as it is economical, simple, and eco-friendly. In this review, the application of apatite and apatite-based composites as high-capacity adsorbents for heavy metal removal from aqueous solution is discussed. Various synthesis routes such as precipitation, hydrothermal, solid-state, ultrasound-microwave, and sonochemical methods are discussed, highlighting their effects on the structural, morphological, and adsorptive properties of apatites. Surface-modified apatites possess outstanding metal adsorption activity for Pb(II), Cd(II), Cu(II), and Cr(VI) through mechanisms by ion exchange, surface complexation, and precipitation. The findings confirm apatite's huge potential as an environmentally friendly approach for heavy metal remediation.
