| Summary: | 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. |
