摘要：
The extent of utilization of the full surface area of Bone Charcoal (BC) for removal of some organic pollutants which are commonly found in wastewater streams is described. The adsorbent is a by -product obtained from Pakin Co., Egypt. In this concern, adsorption isotherms of 2- chlorophenol, m-, p- cresols, 4- nitrophenol, 2,4-dichlorophenol and 2- nitrophenol from aqueous solutions by (BC) have been evaluated. The data conform to both Langmuir and Freundlich adsorption isotherms. Also, possible treatment of industrial wastewater by (BC) was assessed. Assessment of the treatment process was in terms of measuring the Total Organic Carbon (TOC) before and after treatment as a measure for organic contaminants. The sample treated was obtained by Egyptian company for preparing and dyeing of wools, Mostorod. It was found that, treatment of wastewater in batch systems using (BC) coupled with uv-irradiation in the presence of H2O2 is promising.
