Industrial Fermentation Waste Aspergillus niger as Adsorbent for Sequestering Cr6 + from Aqueous Solution
Abstract:
Biosorption of Cr6 + ions by industrial fermentation waste Aspergillus niger free dry mycelium was investigated in a batch system..The influences of Cr6 +concentration, biosorbent dose, solution pH and contact time on Cr6 +were investigated.Optimum biosorption was observed to be 73.5% at pH 5,biosorbent dose 20g/L, initial Cr6 + concentration 100 mg/L. Adsorption equilibrium was established in 800 min at 30°C. The Langmuir model compared to the Biosorption equilibrium data were best described by Langmuir isotherm model, R2=0.9999.
