| Abstract | ||||
| Use of date and olive stones as a raw material available in large quantity in Egypt for producing a low cost activated carbon and characterization in this work. The preparation method entails the impregnation of the dried and crushed stones with activated agent ZnCl2 followed by carbonization at high temperature. The quality of the activated carbon prepared was identified by Physical and chemical characterization. The both prepared activated carbon has very large surface area as well as highly developed micro porosity, with good capacity for iodine and methylene blue removal. The objective of this research was to investigate the potential of the two prepared and commercial available activated carbon as sorbent for removing viruses from water and to delineate the sorption mechanism. Powdered activated carbon successfully removed it under the same condition than granular form with priority for our prepared from stones. Three factors contributed to virus removal: a smaller electrophoretic repulsive force between the virus and the activated carbon particles, a small proportion of pores 1.6 and 3.7 nm in diameter, and a greater hydrophobicity of the virus surface. | ||||
