摘要

Because of Carbofuran residues are carcinogenic and contaminate natural free water, the widespread use of carbofuran poses a serious risk to human health. For purification of water from carbofuran residues, a smart absorber with a designed surface and a low cost becomes crucial. The current study uses unique mixed metal–metal–organic frameworks (M–MOFs) based on different contents of carboxylic group (benzenedicarboxylic acid, benzene-1, 3, 5-tricarboxylic acid, and benzene tetracarboxylic acid) to remove carbofuran from water. The adsorption properties of carbofuran were investigated through the characterization and analysis of Cu–Zn–MOF-H, Cu–Zn–MOF–COOH, and Cu–Zn–MOF–(COOH)2. Carbofuran residues were deposited both chemically and physically onto the Zn, Cu–MOFs. The Langmuir and Freundlich isotherm models were used to study theoretical calculations and modeling on the surfaces of adsorbents. The Langmuir equation best described the carbofuran adsorption data, according to non-linear regression of the experimental data. Carbofuran’s maximal adsorption uptake onto Cu–Zn–MOF-H, Cu–Zn–MOF–COOH, and Cu–Zn–MOF–(COOH)2 were 162.5, 348.35 and 389.2 mg/g, respectively. The pseudo-second-order equation is the kinetic model that fits the data best. The findings demonstrate that as the adsorbent’s carboxylic acid concentration rose, the carbofuran pesticide removal was effectiveness.
