Monolithic material based on molecularly imprinted polymer（ MIP） was developed by using bisphenol A（ BPA） as template. It was then applied to extract environmental estrogens in river water samples. The surface of the MIP monolithic bar was uniform and porous. The bar could be used more than 80 times. The MIP-monolithic bar presents good selective effect to different environmental estrogens in water solution. This study also established a method to analyze estrogens in aqueous samples through MIP monolithic bar microextraction coupled with HPLC. The method was also used to analyze six types of estrogens in river samples,and the recovery rates ranged from 70. 5% to 109. 3%. The MIP-monolithic material microextraction coupled with HPLC can be used to determine numerous types of estrogens in aqueous samples simultaneously.
