“…Non-ionic species present at pH range 2-4, hence the removal of As(III) was not favorable on surface of biosorbent. With the increase of pH, there was gradual increase in interaction between adsorbent surface and charged adsorbate species [30]. At higher pH value the OH -ion starts dominating and thus biosorbent surface becomes negative charge [31].…”

“…Furthermore, the characteristic of the equilibrium time curve exhibited that the SBB process approaches the equilibrium in a short span of time [29]. So, the curves found were single, smooth, and continuous, leading to equilibrium and suggested the probability of monolayer coverage of the adsorbate on the surface of immobilized bacterial cells [30].…”

One of the main environmental concerns of today is the occurrence of arsenic in wastewater. Targeting a solution for this problem, several efforts have been made towards research and application of cost-effective and effortlessly adaptable processes. The ability of a biofilm of Bacillus arsenicus MTCC 4380 supported on sawdust/MnFe 2 O 4 composite to biosorb/ bioaccumulate As(III) and As(V) was investigated in batch experiments. Optimum biosorption/bioaccumulation conditions were determined as a function of contact time and temperature. The equilibrium was achieved after about 220 min at 30°C temperature. Nonlinear regression analysis was done to determine the best-fit kinetic model based on three correlation coefficients and three error functions and also to predict the parameters involved in kinetic models. The results showed that both Brouers-Weron-Sotolongo and Avrami models for both As(III) and As(V) were capable of providing realistic explanation of biosorption/bioaccumulation kinetic. Applicability of mechanistic models showed that the rate controlling step in the biosorption/bioaccumulation of both As(III) and As(V) was film diffusion rather than intraparticle diffusion. The estimated thermodynamic parameters ΔG 0 , ΔH 0 , and ΔS 0 revealed that biosorption/bioaccumulation of both As(III) and As(V) was feasible, spontaneous, and exothermic under examined conditions. The activation energy (E a ) estimated from Arrhenius equation specified the nature of biosorption/bioaccumulation being ion exchange type. The effect of co-existing ions such as Cu 2+ , Zn 2+ , Bi 3+ , Cd 2+ , Fe 3+ , Pb 2+ , Co 2+ , Ni 2+ , Cr 6+ , and SO 4 2− at different concentrations was inspected.

“…Adsorption kinetic plays an important role on the physical and/or chemical characteristics of the sorbent material, which also influenced the sorption mechanism [12]. Although many models like homogeneous diffusion model or the pore diffusion model have been proposed to interpret the transport of solutes inside adsorbents, the mathematical complexity of these models makes them inconvenient for practical use.…”

Abstract-Arsenate (As(V)) adsorption from aqueous solution onto clinoptilolite incorporating iron or aluminum oxides was investigated. The modified samples were characterized by nitrogen adsorption isotherms, TEM-EDX analysis. Kinetic models were applied to describe As(V) adsorption on each modified clinoptilolite samples. The kinetic data, explained best by the pseudo-second-order model by good regression coefficients.
