Abstract :
Today, the excessive using of chemical fertilizers and poisons to produce more crops in all parts of the world is considered a major environmental and health challenge. Diazinon turns into dangerous compounds under certain conditions, especially when the hydrocarbon solvent contains a small amount of 1-2% water and is exposed to heat, light and air. This study was conducted with the aim of synthesizing N-TiO2@SiO2@Fe3O4 nanocomposite as a catalyst with ultra-sonication in the presence of visible light to measuring by products resulting from the molecular synthesis of diazinon from aqueous solutions. Nano catalyst was synthesized by co-precipitation and sol-gel method. In this study, the by-products produced due to the removal of diazinon poison were investigated with GC-MS method. The resulting of spectrum was matched by library search at NIST. The results of the spectra obtained from this research showed that did not match with the spectra obtained from the molecular breakdown of diazinon and no by products were produced.
