Abstract: The design and construction of a high selective voltammetric sensor for propazine by using a molecularly imprinted polymer (MIP) as recognition element were introduced. In order to study the intermolecular interactions in the pre-polymerization mixture and to find a suitable functional monomer in MIP preparation, a computational approach was developed [1-3]. It was based on the comparison of the binding energy of the complexes between the template and functional monomers. Having confirmed the results of computational method, two MIPs were synthesized with functional monomers MAA and AAM, and the result indicated that acrylamide (AAM) is the best candidate to prepare MIPs. The carbon paste electrode modified with molecularly imprinted polymer (MIP-CPE) [4-6] was applied for propazine determination using cathodic stripping voltammetric method. Some parameters affecting the sensor response were optimized and then the calibration curve was plotted. Two dynamic linear ranges of 0.01 – 1.0 μM and 1.0 – 55.0 μM were obtained. The detection limit of the sensor was calculated as 0.001 μM. This sensor was used successfully for propazine determination in food samples
