Abstract: Using hydroquinone as template, acrylamide as monomers, we synthesized MIPM in aquosity system with suspension polymerization,on which surface there are some holes.The absorbance of MIPM to hydroquinone will no longer increased after two hours,it means that it reaches the saturation which were 13.5 μmol L-1.The separate genes of MIPM were 3.4 and 1.46 with phenol and pyrocatechol as competitiors.The MIPM had the better effect of adsorption and selectivity.Using MIPM as molecule recognizates,we set up a new method which was molecularly imprinted technique-flow injection- chemoluminescence analysis to detect hydroquinone.The result shows that the range of hydroquinone concentration from 1 x 10-3 μg L-1 to 7 μg L-1 with adsorbed by MIPM is linearly dependent,which relativity coefficient is 0.9998 and the relative standard deviation is 1.6%, the detection limit is 9.6 x 10-4 μg L-1.Using the method to detecting hydroquinone from the water sample,the recoveries of hydroquinone is 97% - 101%, the result is pretty good. 2011 IEEE
