An optimization study for bio-removal of lead from aqueous environments by alkali modified Polyporus Squamosus

Rapidly increasing industrialization and urbanization cause serious environmental pollution. Discharge of polluting material from various industries such as smelting, mining, ore processing, metal plating into the environment without treatment causes pollution can have dangerous effects on balance. The utilization low-cost adsorbents biological materials a replacement for costly traditional methods adsorption heavy pollutants wastewater was reviewed. This study aimed to investigate biosorption Pb(II) ions aqueous solutions with NaOH-modified Polyporus squamosus biosorbent optimize conditions. Firstly, parameters most influencing response (initial concentration (Co), pH, temperature biomass dose) were determined using Central Composite Design (CCD). optimum conditions evaluated 60.76 mg/L, 6.3, 25 °C, 0.23 g Co, initial dose, respectively. From conditions, yield capacity obtained 93.8% 23.63 mg/g,
