Description
Summary:Pesticide residues in water can cause varying degrees of damage to the ecological system and human health, attracting widespread attention. During this research, a cost-effective, easily synthesized, and high surface area mesoporous poly (melamine–formaldehyde) (mPMF) was employed as an adsorbent to effectively absorb forchlorfenuron (CPPU) pesticide from water. The maximum adsorption capacity and maximum adsorption effectiveness were found to be 231.43 mg/g and 81%, respectively. The study of adsorption kinetics revealed that the adsorption mechanism conforms to a quasi-second-order kinetic model, indicating that chemical adsorption predominates, and the overall adsorption process is influenced by two or more factors. The adsorption isotherm experiment demonstrated that the adsorption mechanism is better described by the Freundlich model, suggesting that mPMF exhibits multi-layer heterogeneous adsorption of CPPU, involving both physical and chemical adsorption mechanisms. Additionally, mPMF showed the potential for cyclic regeneration through desorption after adsorbing CPPU from water, as its adsorption capacity remained largely unaffected even after four consecutive cycles.
