In this study,a novel poly(graphene-methylmethacrylate-ethylene glycol dimethylacrylate)(G-MMA-EGDMA)was synthesis by cryogel method and prepared as the adsorbents for stir bar sorptive extraction(SBSE),respectively,to increase the extraction efficiency and reduce the flow resistance.In the preparation of modified graphene polymer,the acrylate functional group was first modified on the graphene oxide,then mixed with methyl methacrylate and ethylene glycol dimethacrylate for cryogel polymerization in dimethyl sulfoxide(DMSO)at the temperature of 0.5oC.The modified graphene oxide was identified with infrared spectrum,and the porosity of copolymer was observed by SEM image.The porous graphene copolymer was prepared and coated onto the surface of a stir bar as the adsorbent for SBSE of bisphenol A and four alkylphenols in aqueous solution.Parameters affecting the extraction efficiency such as the pH of sample solution,the salt addition,the stirring-rate,the extraction time,and the desorption solution were investigated thoroughly.Results indicate that the optimal conditions for SBSE of bisphenol A and four alkylphenols in 50 mL of aqueous solution without salt-addition can be achieved with the stirring-rate of 400 rpm for 40 min extraction,then desorbed with 100 μL of ethanol for the analysis with HPLC-UV.Under the optimal conditions,the LOD and LOQ for bisphenol A and four alkylphenols were below 0.04 ng/mL and 0.1 ng/mL,respectively.The RSDs were less than 7.2%.Recovery were between 90.5-106.4%and the RSDs were less than 7.2%.These results indicated that the poly(G-MMAEGDMA)based SBSE is a convenience,sensitive,and eco-friendly sampling method.
