摘要：

The use of Phanerochaete chrysosporium biomass for the removal of Reactofix Golden Yellow from aqueous solution and eight textile dyes (four azo and four anthraquinone) from a synthetic effluent (0.6 g/l) at different pH, temperature and biomass concentrations was studied. Adsorption was maximum at pH 2.0 and 40 degrees C using 2.45 g mycelial biomass. The rate constant of adsorption was 1.95x10(-1)/min for Reactofix Golden Yellow and 1.64x10(-1)/min for synthetic effluent. In both cases, the equilibrium data fitted well in the Langmuir but not the Freundlich model of adsorption, and the adsorption was biphasic. Adsorption decreased the COD of Reactofix Golden Yellow and synthetic effluent by 54 and 57%, respectively. Desorption (80-84%) of dyes from P. chrysosporium mycelial surface occurred as the pH increased from 2 to 10.
