Synthetic dyes, such as the Rhodamine B (RhB) dye found in wastewater, can be toxic to<br/>humans and aquatic life; treating it can help mitigate its hazardous effects. This study assessed the<br/>efficacy of desiccated coconut waste (DCW) powder, an agricultural waste product derived from<br/>matured coconut, as an adsorbent precursor for removing synthetic dyes using a batch adsorption<br/>process. Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM),<br/>and an energy dispersive X-ray spectrometer (EDX) were used to characterize the adsorbent before<br/>and after adsorption. Various parameters were optimized, and the adsorption kinetic and isotherm<br/>models were evaluated. The results showed that the optimal conditions for RhB adsorption were a<br/>dosage of 2.0 grams, an initial dye concentration of 40 mg/L, and an equilibrium time of 20<br/>minutes. RhB had an equilibrium removal rate of 82.16% with a qe of 0.341 mg/g. The adsorption<br/>of RhB was found to follow a pseudo-second-order kinetic model at a rate of 2.57 x 10-2<br/><br/>g/mg·min.<br/>Based on the calculations, the Freundlich model describes the best adsorptive removal of RhB.<br/>The model suggests that the adsorption was multilayer and that the DCW has heterogeneous<br/>adsorption sites with an equilibrium constant of 0.0153 L/mg. As a result, this study proved that<br/>using DCW as an adsorbent for wastewater treatment is practical, cost-effective, and efficient. |
