- Abstract
- As a key member of benzoylurea insecticides, lufenuron exhibits a strong potential for bioaccumulationin ecosystems. Here, we report the synthesis of a molecularly imprinted polymer (MIP) and its applicationfor selective extraction of lufenuron from agricultural runoff samples. The morphology and thermalstability of the prepared MIP was characterized by SEM and TGA, respectively. The experimental conditionsfor lufenuron detection were optimized through batch binding assay and response surface methodology(RSM). The MIP showcased a two-fold enhancement in binding capacity of lufenuron (74 mg g 1)relative to non-imprinted polymer (36 mg g 1), when measured through batch binding assay. Using aRSM based on central composite design, the qe value was predicted as 73.6 mg g 1 under optimal experimentalconditions (e.g., pH 8). Furthermore, the percentage recovery of lufenuron was estimated as98.8 ± 1.8% (n = 9). The adsorption kinetics of the MIP followed the pseudo-first-order model with v2value of 0.004 (correlation coefficient of 0.99). The limit of detection for lufenuron using MIP-basedmethod was 3 10 6 mg mL 1. There was no significant decrease in the performance of MIP against lufenuronover five successive cycles.
