Description
Summary:Nowadays heavy metals are reported as priority pollutants, due to their mobility in natural water ecosystems and their toxicity; they are among the most important pollutants in source and treated water, and are becoming a severe public health problem. Cellulose can adsorb heavy metals from solution. In this paper, the inexpensive and effective metal ion (Cu2+) adsorbent from wood-waste materials (sawdust) was investigated using the biosorption process, which is a relatively new process that has proven very promising in the removal of metals ions from aqueous effluents. The results show that the biosorbtion of copper ion occurs with higher yields in alkaline solution (pH= 8.5), the adsorption equilibrium is quickly reached (after 15-30 minutes) and copper ions can be removed extensively from aqueous solution after successive adsorption stages.
