Adsorptive removal of Ni(II) using nickel-resistant dead S. cerevisiae AJ208

Recent trends in environmental pollution urge for immediate resolution of Ni(II) elimination as industrial effluents from wastewater. From that perspective, bioremediation substantiates an effective practice for eliminating Ni(II) using a potential biosorbent. In this study, the Ni(II) elimination efficacy of 5000 mg/L Ni(II) resistant dead S. cerevisiae AJ208 is elaborately explained with physical parameter optimization and established by SEM-EDAX analysis. FTIR study validated that carboxyl, hydroxyl, carbonyl, and amine are accountable for biosorption. Investigational findings fit well in the Langmuir model, representing a single-layered adsorption process. Obtained Langmuir maximum adsorption capability is 201.61 mg/g. The pseudo-second-order model fits well with the experimental data, which signifies chemical adsorption. The experimental data have been analyzed using statistics and a genetic algorithm (GA). Ni(II) resistant dead S. cerevisiae AJ208 could substitute the expensive elimination techniques to decontaminate Ni(II) from industrial wastewater.
