Influence of Solvents and Functional Monomers on Preparation of Methyl Parathion Molecularly Imprinted Polymers

LIU Jiao, MENG Fan-ping (College of Environmental Science and Engineering, Ocean University of China, Qingdao 266100, China)  
In order to separate and concentrate the organophosphorus pesticides in water efficiently, the molecularly imprinted polymers (MIPs) were synthesized by bulk polymerization with methyl parathion as template molecule and ethylene glycol dimethacrylate as crosslinking agent. A number of experiments were conducted to investigate the factors, such as the species and amount of the used solvent and functional monomer, which are likely to be the important factors affecting the recognition properties of MIPs. It was found that both the specific area and swelling ratio of the MIPs prepared vary significantly as the used solvent volume changes, and the MIP prepared with chloroform as the solvent exhibits high selectivity for methyl parathion. The 1H-NMR spectra show that the functional monomer 4-vinylpyridine (4VP) forms stable complex with template molecules via π-π accumulation effect; and the experimental results indicate that the 4VP is more efficient to be used as the functional monomer than other two tested monomers, methacrylic acid (MAA) and acrylamide (MA), especially when the used molar ratio of 4VP to template is 4:1. Moreover, the adsorption isotherm of the MIP prepared with 4VP: template=4:1 was studied, and the Langmuir isotherm analysis shows that the maximum adsorption capacity of this MIP is 625.5μmol·g-1, which is much higher than that of the nonimprinted polymer (NIP) (285.7μmol·g- 1). The above prepared MIP was also used to extract different kinds of organophosphorus pesticides in seawater sample, and it exhibits different affinities toward different pesticides with various molecular structures. It seems that, after improving and enhancing the selectivity of the prepared MIP, it is hopeful to be used to separate and concentrate specially the methyl parathion in water.
