Preparation of Molecular Imprinting Material Based on Silica and Their Application in a Solid-phase Dispersion Extraction Matrix for Methyl Parathion and Heavy Metal
Applying molecular imprinting techniques we prepared a hybrid organic-inorganic surface imprinted silica nanoparticles for specific recognition of methyl parathion.Using amino modified silica nanoparticles as supports,acrylamide as the functional monomer,y-methacryloxypropyl trimethoxy silane as the grafting agent,and methyl parathion as a template,we molecularly imprinted silica nanoparticles in in chloroform.The amino propyl functional monomer can not only direct the polymerization on silicon surface,it c...
