摘要: 提出了一种新的绿色农药缓释剂模型——超分子结构草甘膦缓释剂.依据插层组装理论,以阴离子层状材料镁铝水滑石(MgAl-LDH)为插层主体,以除草剂草甘膦为插层客体,由共沉淀法一步组装得到超分子结构草甘膦插层镁铝水滑石(MgAl-LDH-gly).通过对MgAl-LDH-gly的结构、主客体相互作用及化学组成确认,建立了MgAl-LDH-gly的近似超分子结构模型,并对其缓慢释放草甘膦的可行性进行了分析.

关键词: 超分子结构, 草甘膦插层水滑石(MgAl-LDH-gly), 草甘膦缓释剂

Abstract: A novel design of controlled-release glyphosate with a supramolecular structure has been proposed, according to the shortage of traditional pesticide and controlled-release pesticide at present. On the basis of the concept of intercalation and assembly, glyphosate anion intercalated magnesium-aluminum layered double hydroxides(abbreviated as MgAl-LDH-gly) has been prepared by coprecipitation. According to the crystal structure, the interaction between host and guest anion, and chemical composition of MgAl-LDH-gly, orientation of glyphosate anion between the layers of MgAl-LDH-gly are given.

Key words: Supramolecular structure, Glyphosate anion intercalated magnesium-aluminum layered double hydroxide, Controlled-release fomulation of glyphosate
