Hydroxyapatite-loaded coal gasification slag for synergistic heavy metal adsorption

Summary Lead-zinc mining wastewater contains Pb(II), Cu(II), and Cd(II) that are difficult to remove efficiently. A coal gasification slag-supported nano-hydroxyapatite composite (nHAP-CGS) was prepared via chemical precipitation. The composite achieved removal efficiencies of 97.6%, 94.9%, and 79.8% for Pb(II), Cu(II)...
