Abstract

In this study, the biosorption capacity of chitin based shrimp shell waste (Cht-SSW) was investigated in Zn2+ containing wastewater. Initial findings showed that Cht-SSW is an effective biosorbent due to high porosity and functional groups. Within the scope of the study, the effects of Cht-SSW dose, time, pH, and temperature on the treatment efficiency of Zn2+ were evaluated by batch experiments. As a result of the adsorption process, the Cht-SSW dose = 0.5 g/L, pH = 6.32, and time = 30 min were determined as the optimal conditions, and the maximum Zn2+ removal efficiency under these conditions was obtained as approximately 84.12%. The surface morphology and functional groups of Cht-SSW used in the study were determined using FTIR and SEM. In order to determine the biosorption process, analysis was carried out with kinetic and isothermal models. The results were found to fit best with the pseudo-second-order (R2 = 0.990) for the kinetics and the Langmuir isotherm (R2 = 0.993) for the isotherms. The isotherms and kinetics confirmed that Cht-SSW had a high value of adsorption capacity. The values of ΔH°, ΔS°, and ΔG° showed that Cht-SSW was applicable, spontaneous, and endothermic for Zn2+. In addition, a statistics-based experimental design with a response surface methodology was used to study the effect of process operating conditions, including pH, temperature, and chitin concentration. Experimental results point out Cht-SSW is a biosorbent that eco-friendly, economical, easily available, and efficiently (4e) on the removal of Zn2+ from aqueous solution.
