TL;DR: In this article, a batch system with respect to temperature and initial metal ion concentration was studied and the activation energy of biosorption (E A ) was determined as 25.92 kJ mole −1 using the Arrhenius equation.

TL;DR: In this paper, the effect of salt concentrations on the biosorption of chromium(VI) was investigated. But the results were limited to a single batch of living Dunaliella algae.

TL;DR: It was seen that the mono-component adsorption equilibrium data fitted very well to both the Mono-component Langmuir and Freundlich adsorbption models for both the components and the pH values studied while the multi-component Freundlic adsorptive model adequately predicted theMulti- component adsorbent equilibrium data at moderate ranges of initial mixture concentrations forboth the studied pH values.

TL;DR: In this paper, the potential use of Mowital®B30H resin immobilized dried activated sludge as a substitute for granular activated carbon for removing chromium(VI) was examined in a continuous packed bed column.

TL;DR: In this paper, the simultaneous biosorption of iron (III) (ferric) cations and iron(III)-cyanide complex anions to Rhizopus arrhizus from binary mixtures was studied and compared with single metal and metal cyanide complex ion situation in a batch stirred system.

TL;DR: In this paper, combined biodegradation and internal diffusion effects on the Biodegradation rate of ferrous(II) cyanide complex (ferrocyanide) ions by Ca-alginate gel immobilized Pseudomonas fluorescens beads were investigated as a function of initial ferrocyclanide concentration and particle size in a batch system.
