Biosorption of Arsenic (III) from Aqueous Solutions by Industrial Fermentation Waste Aspergillus niger

Abstract:

Biosorption of As³⁺ ions by industrial fermentation waste Aspergillus niger free dry mycelium was investigated in a batch system..The influences of solution pH, biosorbent dose, As³⁺concentration, and contact time on As³⁺ were studied.The results indicatd that absorption capacity was strongly affected by the solution pH, the biosobent dose and initial As³⁺concentration.Optimum biosorption was observed to be 75% at pH 5.0,biosorbent dose 20g/L, initial As³⁺concentration 800ug/L. Adsorption equilibrium was established in 100 min. Biosorption equilibrium data were best described by Langmuir isotherm model.
