Supported on mesoporous silica nanospheres, molecularly imprinted polymer for selective adsorption of dichlorophen

The imprinted polymers were prepared to absorb dichlorophen (DCP) by using mesoporous silica with ordered pores and high specific surface area. Both scanning electron microscopy and transmission electron microscopy results suggested that the mesoporous silica nanosphere pores had a periodic distribu...
