Effective wastewater treatment techniques are needed to mitigate the effects of water contamination, which is a severe environmental issue. The high adsorption capacity and sustainability of adsorption techniques using biochar from agricultural waste, such as coir pith, have made them appear promising. This work intends to optimize the adsorption procedure utilizing biochar made from coir pith using Central Composite Design (RSM-CCD). The effects of pH, time, adsorbent dosage, and adsorbate concentration were examined on adsorption efficiency. In order to comprehend its structural and elemental characteristics, the synthesized biochar was characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). This study focuses on determining the optimal conditions for maximum adsorption efficiency and contributes to environmental engineering by utilizing agricultural waste for water remediation. The results showed that the biochar removed Crystal violet with a remarkable 72% efficiency, highlighting its potential as a powerful adsorbent for water purification.
