Kinetic, isotherm, and thermodynamic studies for adsorptive removal of basic violet 14 from aqueous solution

In this study, the performance of chitosan based semi-IPN nanocomposite hydrogels for the adsorptive removal of basic violet 14 (BV14) from aqueous solution has been explored. Batch adsorption studies were conducted to determine the effect of various parameters on BV14 adsorption, and optimum values...

description In this study, the performance of chitosan based semi-IPN nanocomposite hydrogels for the adsorptive removal of basic violet 14 (BV14) from aqueous solution has been explored. Batch adsorption studies were conducted to determine the effect of various parameters on BV14 adsorption, and optimum values were reported as pH of 8, the adsorbent dosage of 0.025 g, initial BV14 concentration of 5 mg L(−1) and contact time of 90 min at a temperature of 25 °C. The semi-IPN hydrogel containing 0.5% by weight GO showed the improved adsorption capacity for BV14 compared to the neat hydrogel adsorbent, and the maximum adsorption capacity was 276.21 mg g(−1) with a removal efficiency of 90.4%. Kinetic studies have shown that the pseudo-second-order kinetic model can well describe BV14 adsorption. The equilibrium adsorption data showed the best fit with the Langmuir model. Thermodynamic studies revealed that BV14 adsorption was physical in nature and occurred spontaneously and endothermically. The BV14 removal efficiency above 84% was obtained after five consecutive adsorption-desorption cycles, which has proved the reusability performance of the adsorbent and the recovery potential of BV14 dye. Overall, the results of this study indicated that GO containing chitosan based semi-IPN nanocomposite hydrogel could be an effective and environmentally friendly adsorbent for the successful removal of BV14 molecules from aqueous solution.
