This study endeavors to optimize the resource utilization of waste sludge while mitigating environmental risks associated with Pb2+ contamination. Tartaric acid was used as an activator in production modified biochar (MBC-TA, PBC-TA) extracted from municipal and pharmaceutical a means enhance functional groups on surface its adsorption properties. The research systematically examined various influential factors affecting adsorption, namely adsorbent dosage, reaction time, pH. physicochemical properties were evaluated utilizing scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis, point zero charge (pHPZC) analysis. results revealed that modifications significantly impacted efficiency. kinetic model showed by two sludge-derived more consistent pseudo-secondary model, mainly chemisorption. isotherm models fitted analyzed, it found Langmuir adsorbents behavior, relied monomolecular layer capacity tartaric acid-modified MBC-TA PBC-TA increased 22.58 mg/g 22.86 mg/g, respectively. finding underscores efficacy modification augmenting pollutant removal capabilities materials.
