“…However, very little difference can be noticed compared to those reported for single metals [13]. The same functional groups were clearly involved, and no preferential biosorption could be remarked [35,36].…”

“…The most logical reason for this antagonistic action could be explained as being the competition and affinity for same adsorption sites on the biosorbent in the case of binary metal mixture [32]. The decrease in sorption capacity for the immobilized biomass from binary mixtures was quite comparable to that obtained by others using various biosorbent materials [33][34][35]. On the contrary, presence of Cr (VI) seemed to make no pronounced inhibitory effect on the adsorption of Ni (II).…”

Herein, the adsorption efficiency of biomass based on mutated bacterial strain (Bacillus cereus M 1 16 ) impregnated into calcium alginate towards Ni (II) ions was investigated in batch system. Biomass was characterized by sophisticated instrumental analyses. The influencing process parameters on Ni (II) removal from monometallic system were studied and optimal conditions were ascertained. The performance of such biosorbent on exposure to different metal ions was also evaluated. Especially, this work focused on principal interest in Ni (II) removal in presence of surfactants (Sodium dodecyl sulfate and Triton X-100), where Sodium dodecyl sulfate offered synergetic effect as a function of sorption yield. The best fitted pseudo-second order and film diffusion kinetic model in presence of surfactants provided more suitable prediction reflecting rate controlling steps of Ni (II) removal process. Additionally, experimental data adequately fitted by both Redlich-Peterson and Langmuir-Freundlich dual isotherm model. Thermodynamically the process was found to be spontaneous, endothermic and entropy-driven. Regeneration studies were conducted with a series of five sequential adsorption-desorption cycles. Moreover, biomass proved its worth for effective removal of Ni (II) from simulated inorganic wastewater. Thus, this green chemical approach may have immense potential to be explored in the actual system.

“…The figures illustrate the surface texture and porosity of bark adsorbent with holes and small openings on the surface which increased the contact area. These will lead to pores diffusions during adsorption [12]. Morphological analysis of the raw bark and modified bark showed changes of loose bark into more compact form of adsorbent.…”

Abstract-Mangrove barks Rhizophora apiculata which have been chemically modified in basic condition were used as adsorbent for the removal of nickel and copper ions from aqueous solution. The adsorbent was characterized by SEM images, FT-IR and BET analysis. Effecting parameters like initial pH, initial concentrations of metal ions and contact time were investigated. The adsorption data were well fitted by Freundlich isotherm model. Kinetic data were best described by pseudo-second-order model. Thermodynamic studies showed spontaneous and exothermic nature in the adsorption of Ni(II) and Cu(II) ions by the modified mangrove barks.
