چکیده

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 60 mg/L, pH is 6, biomass volume was 20 with high biosorption capacity of 449 mg/g. FTIR spectral analysis indicated that the amide – NH bending, CH stretching, carboxylic acid, and hydroxylic groups are the main functional groups involved in the complexation of metal ions.

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...

Desulfurization of coal by HNO3 leaching: Optimization of influential factors using Box-Behnken design

Sulfur is one of the most significant impurities in coal, which reduces the quality of coal and also results in environmental pollution. This work was aimed to investigate the removal of sulfur from coal by the leaching method employing parameters expected to affect the removal rate such as acid concentration (10-30%), temperature (40-80 °C), and reaction time (40-100 min). A response surface m...

Adsorption and Optimization Removal of Co(tsPc)-4 from aqueous solution using Nanoalumina

In the present study, adsorption of Co(tsPc)-4 using γ-Alumina was investigated. γ-Alumina was prepared by gel combustion method. The XRD pattern revealed that the synthesized γ-Alumina is amorphous and SEM image showed its nanosize scale while BET surface area about 501 m2/g and pore size of 7 nm implies highly porous surface which is a characteristic property of a high-quality adsorbent. In t...
