STUDIES ON BIOSORPTION OF NICKEL USING IMMOBILIZED FUNGUS, RHIZOMUCOR TAURICUS

Studies on Biosorption of Nickel Using Immobilized Fungus, Rhizomucor Tauricus

Rhizomucor tauricus, an industrial fungus, was immobilized in sodium alginate and used as adsorbent for the removal of nickel from aqueous solutions. The biosorption capacity of Ni(II) was found to be 394 mg/g of immobilized biomass. It was observed that an increase in pH from 3 to 6 increased the percent adsorption, and an increase in liquid-to-solid ratio from 2 to 10 increased the metal upta...

Optimization of Ni (II) removal on Rhizomucor tauricus by using Box-Behnken design

Rhizomucor tauricus is used in the production of lipase, after several cycles it is disposed off as biological waste. A new biosorbent material fungus, Rhizomucor tauricus was immobilized, used as an adsorbent for removal of Nickel (II) and for optimization Box-Behnken design used by statistica 6.0. The time required to reach equilibrium was found to be 4 hours. The optimized concentration is 6...

Biosorption of Nickel Ion by Chitosan-immobilized Brown Algae Laminaria japonica

Highly toxic nickel is released into the environment from a number of industrial processes, but current techniques for its removal are expensive and may cause secondary pollution. We developed a biosorbent of chitosan-immobilized brown algae (Laminaria japonica). The effects of different parameters on the adsorption capacity and biosorption-desorption of Ni from aqueous solution were evaluated....

Biosorption of nickel(II) ions on Baker's yeast

The biosorption of nickel(II) ions by deactivated protonated yeast was investigated with respect to the initial pH and initial metal ion concentration. The kinetics of sorption was also followed based on the amounts of metal sorbed at various time intervals for different yeast doses. The equilibrium data could be fitted by the Langmuir isotherm model. The adsorption capacity was pH dependent wi...
