Pomegranate (Punica graantum) Peels as an Agricultural Waste for Removing of CD(II), CR(VI), CU(II), NI(II), PB(II) and ZN(II) from Their Aqueous Solutions

Pomegranate (Punica graantum) peels as an agricultural waste was used as an adsorbent for removal of Cd, Cr, Cu, Ni, Pb and Zn ions from simulated aqueous solutions. The adsorption process was carried out using the batch method. Various effective parameters such as pH, initial metal ion concentration, and adsorbent dose, shaking time, particle size and temperature were investigated. Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM) of Punica graantum peels were done. The efficiency of Punica graantum peels toward removal of metal ions was ordered as Pb2+ \u3c Cr6+ \u3c Cu2+ \u3c Cd2+ \u3c Zn2+ \u3c Ni2+, with the corresponding values of 92.8%, 84.6%, 52.8%, 38%, 25.4% and 22.8%, respectively
