Abstract
The discharge of dye-laden wastewater from the textile sector has a significant impact on water pollution, creating environmental challenges. This contamination generates extensive effluents containing various dye compounds, which alter the environmental conditions. To address this issue, there is a growing need to develop alternative adsorbents using economically feasible raw materials such as locally sourced industrial waste and mineral by-products. A recent study focused on using pomegranate peels and Prosopis Juliflora as adsorbents for dye removal, comparing their adsorption capacities and delineating the adsorption mechanisms using isotherm models. Batch experiments were conducted to evaluate the adsorption capacity of different adsorbents at different doses (0.5, 1, 1.5, 2 and, 2.5 g/100) and initial adsorbate concentrations of 50mg/L. The study examined the adsorption capacity of pomegranate peels and Prosopis Juliflora for basic violet dye in simulated wastewater. The results showed that pomegranate peel exhibited maximum efficiency at an adsorbent dosage of 15 g/l. Optimization studies were conducted, which identified pH 3, a contact time of 20 minutes, and a rotational speed of 120 rpm as the optimal conditions for achieving maximum removal efficiency. Prosopis Juliflora exhibited maximum efficiency at an adsorbent dosage of 15g/l, with subsequent optimization identifying pH 7, a contact time of 15 minutes, and a rotational speed of 120 rpm as the conditions yielding maximum removal efficiency. By adjusting the adsorbent dosage, pH, contact time, and rotational speed, the highest removal efficiency of basic violet dye was discovered. Prosopis Juliflora demonstrated the highest adsorption capacity at 92%, while pomegranate peel demonstrated an adsorption capacity of 82%. Based on this study, it can be inferred that adsorbents derived from Prosopis Juliflora and pomegranate peels can serve as alternative agents for pollutant removal from aqueous environments.
