Abstract
Abstract In recent years, water contamination by pharmaceutical compounds and personal care products (PPCPs) has become increasingly severe. This study synthesizes and evaluates the efficacy of three metal-azolate frameworks as precursors for porous carbon materials to remove pharmaceuticals from aqueous solutions. The synthesized MAF-derived porous carbons (MDPCs) were tested as adsorbents for sulfamethoxazole and other pharmaceuticals in aqueous solutions. Kinetic analysis showed that all MDPCs fit the pseudo-second-order reaction model. The adsorption isotherm was analyzed using the Langmuir adsorption model, suggesting monolayer adsorption in micropores. Additionally, MDPCs demonstrated effective adsorption capacity for PPCPs such as not only sulfamethoxazole, but also metronidazole, oxybenzone-4, and ibuprofen.
