The present work deals with the use of chemically activated sawdust as an adsorbent for the retention of copper (II) ions from synthetisized aqueous solutions. Experimental measurements were carried out batchwise in order to investigate the effects of various parameters such as contact time, pH of the solution, initial concentration of the metallic ion and adsorbent dose. The Langmuir and Freundlich...
The presence of heavy metals in industrial wastewaters, can be an important source of pollution, and may be a severe health hazard, due to their toxicity and to the fact that they are not amenable to biological degradation. Copper is a typical environmental heavy metal pollutant. It is considered in the present study since at high concentration exceeding certain limits, it may cause severe mucosal...
