Phosphate compounds, particularly bioavailable forms like PO₄³⁻, are critical contributors to eutrophication. In this study, MgO-KOH/biochar was used as a binding agent in the Diffusive Gradient Thin Films (DGT) technique enhance phosphate detection. The adsorbent synthesized from biochar derived palm oil waste, activated with KOH increase surface area, and combined MgO for enhanced adsorption efficiency. process followed pseudo-second-order kinetic model, indicating that chemical interactions dominated mechanism. Under different pH levels concentrations, material showed good selectivity orthophosphate, achieving an capacity of approximately 100 mg/g. Characterization via FTIR, XRD, SAA confirmed successful synthesis its structural properties, which contributed performance. Additionally, DGT device demonstrated better efficiency adsorbing PO₄³⁻ compared conventional ferrihydrite-based systems, positioning it highly effective tool monitoring phosphates aquatic environments.
