The adsorption/ biosorption of Hg+2 and furfural from simulated water using granule activated carbon and granule dead anaerobic sludge were investigated. Batch type experiments were carried out to find the equilibrium isotherm data for single and binary system. Ten isotherm models were used for single component and four models for binary system. Langmuir model gave the best fitting for the single system, while the binary system was fitted successfully with extended Langmuir model. FT-IR analysis was carried out before and after adsorption/biosorption to determine which functional groups were responsible for binding the Hg+2and furfural. Kinetic study showed that pseudo- second order model was well fitted for Hg+2 and furfural. R2 used to enhance the justification analysis for each used model.
