SPHAGNUM MOSS PEAT: A GREEN AND ECONOMICAL SORBENT FOR REMOVAL OF HEAVY METALS (Cd and Cr) FROM WASTEWATERS

Sphagnum moss peat, an inexpensive natural material, was used to remove cadmium and chromium from aqueous solutions. The sorption experiments in batch systems show that the removal performances of the peat were greatly dependent upon the pH solution and metal ion concentration. The removal of Cd (II), Cr (III) and Cr (VI) species occurs by different mechanisms. The Cd
