Palm fibers (PF) were estimated for the wastewater treatment. An investigation into the effects of varying dosages, starting concentrations, pH, and contact time was conducted in a lab setting to assess palm fiber's potential as a bioadsorbent in the treatment of wastewater. The palm fibres were characterized using different experimental approaches. The adsorption procedures were obtained to be contact time (90 min), pH-dependent (6.0), dose (25 g), and the height removal efficiency appeared at a starting concentration of 100 mg/L. Under these circumstances, the COD removal effectiveness of (PF) was almost 76%. Room temperature equilibrium adsorption studies were conducted and compared to the Freundlich and Langmuir models. The outcomes for the removal of COD by palm fibre (PF) are noteworthy, and this technique may prove to be an affordable wastewater treatment option.
