Abstract

It is becoming more and more critical to identify and eliminate pesticide residues that are intended to be used in combating agriculture but pose a threat to all living things due to their unconscious use. In this study, a high- performance molecular imprinted material (MIP) was synthesized to remove ziram, a dithiocarbamate fungicide, from its liquid phase. After characterization studies of the printed polymer synthesized by the suspension poly- merization process, the re-bonding ability and the suitability of the adsorption process to kinetic and isothermal models were compared with an non-imprinted reference polymer (NIP). Selectivity of MIP adsorbent prepared by imprinting method against template molecule ziram; their adsorption ability against different dithiocarbamate fungicides (maneb, ferbam, and propineb) was determined by testing. Some extraction parameters were opti- mized to evaluate the extraction performance of MIPs used as adsorbents in the solid-phase extraction column. It has been found that under optimized conditions, the developed MIP-SPE method provides high recovery for ziram. This method was developed; it was determined that MIP-SPE showed higher extraction efficiency against ziram than commercial C18-SPE and non-print polymer solid-phase extraction (NIP-SPE) processes. Thus, the MIP-SPE method has proven to be an environmentally friendly, sensitive, easy-to-work, time-saving, efficient sample pretreatment method that uses less solvent. These findings will provide a fundamentally technical for the removal of the trace hazardous pollutants.
