摘要

Sugarcane bagasse, a biomass residue generated from the sugarcane industry, has demonstrated excellent potential as an effective adsorbent. In this study, a sugarcane bagasse surface molecularly imprinted polymer (MIP) was synthesized using methacrylic acid (MAA) as the functional monomer and carbaryl as the template molecule. The synthesized material was characterized. The selective MIP was employed for the preconcentration of carbamate insecticides prior to chromatographic determination. Various experimental parameters were systematically investigated and optimized. Under the optimized conditions, the method exhibited a wide linear range with coefficients of determination (R2) greater than 0.99. Limits of detection (LOD) and quantification (LOQ) were achieved in the ranges of 0.0006–9.0 µg L−1 and 0.002–30.0 µg L−1, respectively. High enrichment factors reaching up to 18.37 were obtained for all analytes. These findings highlight the significance of developing specific sorbents based on sugarcane bagasse for the enrichment and determination of carbamate residues in rice matrices.
