Abstract
Biosorption behavior of Pleurotus mushroom spent-substrate was studied using two divalence cations: Ni(II) and Cu(II). Biosorption of both cations showed similar behavior on the effect of pH, initial concentration, temperature and contact time. Optimum biosorption was found to be between pH of 5-6, while lower initial concentration and temperature (as low as 10 mg.L-1 and 5 °C), increased the biosorption efficiency. Rapid biosorption was observed to occur within 4-5 minutes of contact time. Therefore, metal removal using PMSS as the biosorbent needs to address the four fundamental parameters.
