Abstract:
The biosorption of metanil yellow on hen egg membrane from
aqueous solution in a batch process was investigated at ۲۹oC with
a view to determine the potential of the membrane in removing
metanil yellow from aqueous solution. The effects of contact time,
initial biosorbate concentration, biosorbent dosage and initial
biosorbate pH were determined. Various isotherm models were used
to analyze experimental data. The highest experimental equilibrium
biosorption capacity obtained was ۱۲۹.۸۸ mg g-۱. The optimum pH
was ۳. Adsorption capacity increased with increase in initial solution
concentration but decreased with increase in time. The isotherm
models applied were good fits based on correlation coefficients.
Flory-Huggins isotherm was the best fit (R۲ =۰.۹۸۶). The biosorption
was endothermic, good, physisorptive and spontaneous. This work
shows that hen egg membrane is a potential biosorbent for the
removal of metanil yellow from aqueous solution.
