Synthesis of Nonylphenol Surface Imprinted Polymer Microspheres and Their Molecule Recognition Characteristics
摘要
Abstract
By using surface molecular imprinting technique, a molecularly imprinted polymer(MIPs) for nonylphenol (NP) was synthesized on the surface of silica microparticles(SiMPs) with NP as template molecule, 2-methacrylic acid(MAA) as functional monomer and vinyltrimethoxysilane( VTFS) as grafting agent. The homogeneous dispersion of microspheres and larger specific surface area of the SMIP were observed by means of scanning electron microscopy (SEM) and BET adsorption apparatus. The characteritic of chemical structures in the modification procedure of MIP was studied by fourier transform infrared spectroscopy( FTTR) , and the adsorption property between the template molecule and functional polymer was evaluated by equilibrium adsorption method. The results indicated that the maximum adsorbing capacity of SMIP to NP was 184. 6 mg/g. In addition, the adsorption capacity of SMIP to NP was higher than those of its structural analogues, e. g. p-octylphenol and bisphenol A, indicating that SMIP has a good recogntion capacity to NP.关键词
