BIOREMOVAL OF DRIMARINE YELLOW HF-3GL BY IMMOBILISED HYBRID BIOSORBENT

摘要

The water pollution is one of the environmental problems due to the bioaccumulation tendency of toxic materials. The purpose of this study was to treat wastewater through bioproccsses for removal of Drimarine Yellow HF-3GL from aqueous solutions in batch mode. The biosorption characteristics of immobilised heat inactivated hybrid biosorbcnt (HI HB) and Active hybrid biosorbcnt (Active HB) for dye removal were evaluated as a function of contact time, pH, initial dye concentration and temperature. Maximum uptake of Drimarine Yellow HF-3GL was 7.82 and 30.87 mg/g at pH 3 by immobilised HI HB and Active HB. The Langmuir isotherm described well the biosorption process. The kinetic data fitted well to the pseudo-second order kinetic model.
