Abstract
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.
