Abstract

The invention discloses application of a cyclodextrin metal-organic framework carbon material in water treatment and fertilizer slow release. A precursor to the carbon material herein is a beta-cyclodextrin metal-organic framework (beta CD MOF) made by subjecting beta-cyclodextrin and potassium benzoate to reaction, and the beta-cyclodextrin metal-organic framework is subjected to sintering at a high temperature under nitrogen protection to obtain the cyclodextrin metal-organic framework carbon material. The cyclodextrin metal-organic framework carbon material has rich pore structure, rich active sites to act with herbicide molecules and rich potassium; therefore, the cyclodextrin metal-organic framework carbon material may act as a multifunctional environmental material to remove herbicides in water and act as a slow-release potassium fertilizer; a novel economic effective strategy to solve pesticide residue and overuse of chemical fertilizers is provided.

Description

technical field [0001] The invention generally relates to the field of environmental pollution restoration and fertilizer technology, and in particular to an application method of a β-cyclodextrin metal-organic framework carbon material. Background technique [0002] Agricultural water consumption accounts for about 75% of the world's total water consumption. Therefore, the treatment of agricultural sewage and reuse in agricultural production activities can effectively achieve a virtuous cycle of water and sustainable use of water resources. Due to the extensive use of pesticides in farmland, a large amount of pesticides often remain in agricultural wastewater. Agricultural recycled water is often used for agricultural irrigation, and the use of recycled water containing pesticide residues will cause crop phytotoxicity and pose a threat to environmental ecological security. Therefore, solving the pesticide residues in agricultural wastewater is the core issue of agricultura...
