Environmental pollution due to the development in technology is one of the most important current problems and of the future. Heavy metals such as copper, lead, …etc in wastewater are hazardous to the environment. Theses metals cannot be degraded or readily detoxified biologically and have tendency to accumulate in living materials. Also, heavy metals in the wastewater discharged to main water bodies can be toxic to aquatic life and render natural waters unstable for human consumption.
Copper (Cu) is a priority metal pollutant introduced into water bodies from many industrial processes such as metallurgical industry, fertilizers manufacture, paint manufacture and petroleum refining. An effort has been made in the present study to evaluate the potential of locally prepared activated carbon (LPAC) prepared from oil cake waste as an adsorbent (a low cost material) to remove Cu from aqueous solutions by adsorption technique. The effect of various parameters such as initial concentration of Cu, contact time, and solution pH on adsorption efficiency were studied during batch experiments at room temperature. The experimental results obtained during the study fitted well with Langmuir isotherm better than Freundlich isotherm. The maximum adsorption capacity of LPAC was high, that indicated the suitability use of LPAC. The percentage removal of Cu from aqueous solutions was high especially for solutions that had initial concentrations less than 100 ppm. The results obtained from this study show that, the LPAC can be used as low cost material for reliable removal of Cu from water and wastewater effluents.
