Synthesis and characterization of a molecularly ımprinted polymer adsorbent for selective solid-phase extraction from wastewater of propineb

Abstract

Pesticide residues, which have become a critical problem today, negatively affect the living life and cause concern for the future life. Different methods are being developed to eliminate the problems caused by pesticides and pesticide residue analysis. In this study, a new molecularly imprinted polymer (MIP) has been synthesized for using methacrylic acid as the functional monomer and propineb, a fungicide, as the template molecule. The selectivity and binding properties of MIP were compared with non-imprinted polymer (NIP). MIP particles were used as an adsorbent in the solid-phase extraction column, and various extraction parameters were extensively optimized to evaluate the extraction performance. It was determined that under optimum extraction conditions, MIP showed higher selectivity and extraction capacity toward propineb compared to commercial C 18 column and NIP. As a result, the developed solid phase extraction method was optimized for propineb residue analysis, and high extraction efficiency was obtained. This method, which is low cost, requires very little use of organic solvents, is fast and easy, is selective and environmentally friendly, is very useful for the purification of wastewater from pollutants.
