【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 (Mg Al-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 (Mg Al-LDH-gly) .通过对 Mg Al-LDH-gly的结构、主客体相互作用及化学组成确认 ,建立了 Mg Al-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 .更多还原

【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.更多还原
