Pleurotus spent mushroom compost is usually discarded as agricultural waste. This study investigated the biosorption characteristic of copper by Pleurotus spent mushroom compost. Parameters including biosorbent concentration, initial pH, contact time, initial copper (II) concentration and temperatures were examined in batch mode. Half saturation constant of copper (II) biosorption was obtained at 1.4 %(w/v) biosorbent concentration, unadjusted pH of 5.5, 10 minutes contact time and at 50 mg/L copper (II) solution. Copper (II) biosorption process well fitted to Langmuir isotherm and pseudo second order kinetic model. Generally, biosorption was not a spontaneous exothermic reaction. Rapid biosorption process and highly potential in reusability of Pleurotus spent mushroom compost are very useful for pilot or industrial wastewater purification application, which to be favorable for the continuous and reusable operation in a column.
