Abstract

In recent years color removal from textile effluents on an industrial scale has received a lot of attention not only because of its potential toxicity but also because of its visibility issue. The current study investigated the use of Banana Peel (BP) as a low-cost adsorbent for Reactive Red 43 (RR43) and   Malachite Green (MG) removal from aqueous solution. There are numerous color removal techniques, the most common of which is adsorption. The practical performance evaluation in a batch reactor is carried out due to its feasibility of operation. In our batch system, we looked at variables like initial dye concentration, contact time, adsorbent dose, and solution temperature. Thermodynamic, kinetic, and adsorption isotherm studies have all been evaluated. The adsorbent was characterized using different techniques. The equilibrium data was analyzed by Langmuir and Freundlich isotherm and showed a good fit with the Freundlich isotherm (R2=0.964 for RR43,0.996 for MG). kinetic data were analyzed using pseudo-first order and pseudo-second order kinetic, the adsorption kinetics data were fitted to pseudo-second order kinetic with a good agreement with the intra-particle diffusion model. The parameters of thermodynamic including enthalpy ΔH°, entropy ΔS° and free energy ΔG° demonstrated that the adsorption process was feasible, spontaneous, and exothermic in nature. The results clarified that optimized conditions were (2.15, 6.3) solution pH for RR43 and MG respectively,10mg/L initial dye concentration, adsorbent dose 0.1 gm/20 ml, and adsorption time 80 min,100 min for RR43 and MG respectively, and (92.82% and 82.52%) of RR43 and MG were removed by BP at experimental optimum conditions. The experimental results show that BP has good potential as a bio-sorbent to remove the colour from textile effluent and as an alternate low-cost adsorbent.
