Abstract

Recently, cost-effective and rapid analysis of carbendazim, in surface, drinking and ground water has attracted a huge deal of interest. Nevertheless, for given applications, the use of present biological receptor-based sensing approaches is limited based on the costs and stability. Hence, the best alternatives are the cost-effective and robust imprinted polymeric receptors. The current study deals with synthesizing MIPs (molecularly imprinted polymers) for carbendazim utilizing methacrylic acid in chloroform as a porogen. The MIP’s binding affinity with carbendazim was assessed in aqueous media. Superior imprinting features for carbendazim were found by MIPs synthesized in chloroform. Imprinted polymers were prepared using bulk polymerization, by mixing MAA as a functional monomer, carbendazim as a template, EGDMA as a cross-linker and AIBN as a initiator were dissolved in chloroform. Here, it was demonstrated carbendazim MIPs merged into a CP (carbon paste) electrode as a MIP-CP sensor platforms to detect the carbendazim. By this simple sensor format, precise determining of carbendazim is allowed utilizing an electrochemical method. We have achieved a detection limit of 3.1 × 10− 8 mol L− 1 for this compound in linear range of 0.1–100 μM. By the simple procedure, low production cost, and easy preparation, the MIP sensor becomes attractive for sensitive and selective detection of analytes, even in less-armed laboratories with nominal training.
