Adsorptive Removal of Ibuprofen, Ketoprofen and Naproxen from Aqueous Solution Using Coconut Shell Biomass

The use of commercial activated carbon (AC) to remove organic micropollutants from aqueous solution is expensive and unsustainable. In this study, coconut shell (CSAC) was synthesized applied for the removal ibuprofen, ketoprofen naproxen solutions. effects carbonization acid activation on CSAC were studied using Fourier-transform infrared spectroscopy, scanning electron microscope, proximate ultimate analyses. influence initial concentration (200–1000 mg/L), contact time (10–200 min), temperature (30–60°C) also investigated. adsorptive capacity various pollutants found increase with up 150 min. Ibuprofen, obeyed Langmuir (R2 = 0.9978), Temkin 0.9551) Freundlich 0.9879) isotherm, respectively. kinetic data obtained are best described by pseudo-first-order model correlation coefficient values in range 0.96–0.99. free energy ( G) ranged between 1.0 9.0 kJ/mol all mechanism adsorption physical, endothermic, non-spontaneous. This study shows that an effective alternative adsorbent sequestering mixture solution.
