Molecular imprinting technology is becoming a versatile tool for the preparation of tailor-made molecular recognition elements. An innovative electrochemical sensor which enables the recognition of a small pesticide target molecule atrazine based on molecularly imprinted polymer (MIP) is developed. The MIP has been synthesised by using bulk polymerisation method. Further attachment of the polymer onto the graphite felt activated the MIP-electrode for electrochemical sensor. The obtained sensing MIP is highly specific towards newly added atrazine and the recognition can be quantitatively analysed by the variation of the cyclic voltammogram of hybrid MIP-electrode. The developed sensor shows remarkable properties with 1.2 of imprinting factor with binding capacity of 4.06 ± 0.8 mg g−1 of polymer.
