Batch and continuous biosorption of chromium(VI) by Rhizopus arrhizus
TL;DR: In this article, the Langmuir, Freundlich and Redlich-Peterson adsorption isotherm models were used in the equilibrium modeling of chromium-alginate gel beads.

Application of response surface methodology for the biosorption of copper using Rhizopus arrhizus
TL;DR: The analysis of variance (ANOVA) of the quadratic model demonstrates that the model was highly significant and a maximum copper removal of 98% was obtained using the biosorption kinetics of copper under optimum conditions.

Biosorption of zinc (II) by Rhizopus arrhizus: equilibrium and kinetic modelling
TL;DR: In this article, the adsorption of zinc (II) ions on Rhizopus arrhizus, a filamentous fungus, was investigated in a batch reactor, where a contact time of 120 min was required to reach equilibrium.
Bioaccumulation of chromium(VI), copper(II) and nickel(II) ions by growing Rhizopus arrhizus
TL;DR: In this paper, the metal resistance capacity and metal ion accumulation capacity during the growth of Rhizopus arrhizus and the inhibition kinetics of heavy metals, namely chromium, copper and nickel were studied in a batch reactor.
