INVESTIGATION OF ISOTHERMAL PARAMETERS OF DYE ADSORPTION ONTO ACTIVE CARBON

The fact that active carbon adsorps colourants and heavy metals has been known for a long time and thus it is used as adsorbant in removal of such pollutants. In this study, the capacity of active carbon in removal of colourant was investigated. As active carbon, Zivzik pomegranate from Siirt district of TURKEY was used and removal of colourants of Methylene Blue and Crystal Violet was studied. Active carbon was prepared with ZnCl2 by chemical activation. BET surface area, total surface volume and surface area of active carbon were measured by hte istrument called BET. In our study, adsorptions Methylene Blue and Crystal Violet colourants to active carbon at 45°C were evaluated for four different initial colourant concentrations of 200, 400, 600 and 800 mg/L graphically.
