Date palm leaflets were used as a precursor to prepare dehydrated carbon (DC) via phosphoric acid treatment at 150&#x2103;. DC, acidified with H<sub>3</sub>PO<sub>4</sub>, was converted to activated carbon (AC) at 500&#x2103; under a nitrogen atmosphere. DC shows very low surface area (6.1 m<sup>2</sup>/g) while AC possesses very high surface area (829 m<sup>2</sup>/g). The removal of lisinopril (LIS) and chlorpheniramine (CP) from an aqueous solution was tested at different pH, contact time, concentration, and temperature on both carbons. The optimal initial pH for LIS removal was 4.0 and 5.0 for DC and AC, respectively. However, for CP, initial pH 9.0 showed maximum adsorption on both carbons. Adsorption kinetics showed faster removal on AC than DC with adsorption data closely following the pseudo second order kinetic model. Adsorption increases with temperature (25&#x2103;&#x2013;45&#x2103;) and activation energy (E<sub>a</sub>) is in a range of 19&#x2013;25 kJ mol/L. Equilibrium studies show higher adsorption on AC than DC. Thermodynamic parameters show that drug removal is endothermic and spontaneous with physical adsorption dominating the adsorption process. Column adsorption data show good fitting to the Thomas model. Despite its very low surface area, DC shows ~70&#x25; of AC drug adsorption capacity in addition of being inexpensive and easily prepared.
