Encapsulation of Pesticide Nanoparticles Using Polymerized Carbon Nanotubes and Application of Synthesized Nanocomposite for Alternaria Alternata Fungi

摘要

Polymerization of citric acid onto the surface of oxidized multi wall carbon nanotubes was led to MWCNT-graft-poly (citric acid) (MWCNT-g-PCA) hybrid materials. Trapping of pesticides such as Benomyl, Trichlorfon and Pymetrozine (chess) in aqueous solution by MWCNT-g-PCA hybrid materials was led to Encapsulated Pesticide (EP) into polycitric acid shell. Optimum condition for encapsulation of Benomyl, Trichlorfon and Pymetrozine in hyper branch polycitric acid such as pH, stirring time and temperature was investigated by UV-Vis spectroscopy method. Also encapsulation of pesticides on CNT-g-PCA hybrid material were confirmed via TEM analysis. Furthermore the effect of encapsulated Benomyl on Alternaria alternate fungi was investigated. Experiments indicated that encapsulated Benomyl in comparison with bulk Benomyl had superior toxic influence on Alternaria alternata fungi.
