| Abstract |
An industrial waste fungus Rhizomucor tauricus mycelial
biomass was entrapped into alginate gel liquid curing
method in the presence of Ca (II) ions. The Biosorption of
cadmium (II) by the entrapped live biomass and dead powdered
fungal biomass has been studied in a batch system.
The binding capacity of immobilized live fungal biomass
was very high comparative to dead powdered fungal biomass.
The effect of initial metal concentration, pH, temperature
and L/S ratio on cadmium removal has been investigated.
The maximum experimental biosorption capacities
for entrapped live and dead powdered fungal of
Rhizomucor tauricus were found to be 79.9 ± 2.2 mg Cd
(II) L-1, 57.29 ± 3.4 mg Cd (II) g-1 respectively. The kinetics
of cadmium biosorption was slow; approximately
75% of Biosorption takes place in 2 hours. The biosorption
equilibrium data were well described by Freundlich adsorption
isotherm. The FTIR results revealed that the functional
groups -OH and -NH2 involved in the biosorption
process. |
