Abstract
The present study investigated the adsorption of Cu, Cd from polluted water onto different compost materials. The treatment has been attempted via batch experiments under various solution concentrations. It probes mainly three adsorbents. The metal initial concentration solutions were ranging from 0 to 50000?g/g. Characterizations of the adsorbents was one of the key focal areas of experiment investigation. Adsorbents were characterized by using Fourier transform infrared spectroscopy revealed that the metal binding is perhaps mainly due to the ionic interaction of the metal cations with the carboxyl groups in the humic substances. Scanning electron microscope was utilized for morphological analysis of the adsorbent and revealed changes in compost composition that could be related to the mechanism of metal adsorption. Energy dispersive X-ray spectroscopy used before and after the metal was loaded, thus gave evident on compost adsorption of heavy metal and metals involvement in the interaction with metal ions by ion exchange. The initial and after adsorption concentrations of the metals were determined using Atomic Absorption Spectroscopy. Higher amounts were adsorbed from Cu followed by Cd. The data fitted well to Langmuir model.
