Abstract
Application of dead macrofungus, Fomotopsis carnea for the sorption of three cationic dyes viz., Orlamar Red BC (ORBG), Orlamar Blue G (OBG) and Orlamar Red GTL (ORGTL) has been investigated. This study mainly focuses on the effect of various sorption kinetic parameters for the u ptake of ORBG. Fomitopsis carnea shows excellent sorption potential fo r all the dyes studied. Saturation capacities for ORBG, OBG and ORGTL are 503.1, 545.2 and 643.9 mg g(-1) respectively. Biosorption in the b atch adsorber can be described by first-order reaction kinetics. Sorpt ion decreases with decrease in pH. Copyright (C) 1996 IAWQ.
