Abstract: This paper addresses the specific ability of molecular imprinted polymers (MIPs) to bind the template. MIPs for atrazine with various monomer:template and crosslinker:template ratios were prepared using bulk polymerization process. In order to obtain conditions closer to real wastewater test cases, the degree of the imprinting factor by the selection of solvent (methanol and water) was studied and compared. The polymer tested in methanol did not demonstrate good recognition of atrazine. In addition, the imprinting factors increased significantly when the imprinted polymers were tested in water solvent by 45%. Based on Scatchard analysis, the MIP was dependent upon low atrazine concentration (up to 40 mg/L) as the cavities formed in the MIP proved the cavities effects. An electrochemical analysis was done in order to prove that the method can be used as a quantitative analysis of atrazine concentration detection in water solution
