三维Al-TCPP MOF纳米片对16种三唑类杀菌剂的吸附去除研究
Adsorption and removal of 16 triazole fungicides by three-dimensional Al-TCPP MOF nanosheets
摘要
Abstract
Triazole fungicides are widely used in agricultural production,and the residues could transmit into water bodies through environmental media,posing a threat to the ecosystem and human health.In this study,aluminum chloride hexahydrate and tetra(4-carboxyphenyl)porphyrin(TCPP)were used as functional monomers to prepare three-dimensional Al-TCPP metal organic framework(MOF)nanosheets,and Al-TCPP nanosheets were used as adsorbents to construct an efficient adsorption and removal method for 16 triazole fungicides in water.The effects of Al-TCPP nanosheets dosage,adsorption time and pH value on the adsorption performance of triazole fungicides were investigated,and the best adsorption removal conditions were obtained.Three typical fungicides were selected to study the adsorption kinetics,adsorption isotherm and adsorption thermodynamics of Al-TCPP nanosheets.The results showed that the adsorption of triazole fungicides by Al-TCPP nanosheets was a monolayer chemical adsorption,which conformed to the quasi-second-order kinetic model.The adsorption process was spontaneous exothermic reaction,and low temperature was beneficial to the reaction.The established method was used to adsorb triazole fungicides in different environmental water samples,and the results showed that the removal rates of Al-TCPP nanosheets for 16 triazole fungicides in different environmental water samples were all higher than 85%.In summary,Al-TCPP nanosheets have good practicability for the adsorption and removal of triazole fungicides,which can provide new idea and novel methods for the study of residue removal of triazole fungicides in environmental water.关键词
