Abstract

A triazine-based covalent organic framework (COF-RC) was synthesized via Schiff-base condensation between 2,4,6-trihydroxybenzene-1,3,5-tricarbaldehyde and 1,3,5-tris(4-aminophenyl)triazine and applied as a sorbent for the solid-phase extraction of seven carbamate pesticides from fruits. COF-RC was characterized by PXRD, FTIR, nitrogen sorption, and TGA, confirming a crystalline microporous framework with a BET surface area of 910 m2/g, a pore size of 16.0 Å, and high chemical and thermal stability. Key SPE parameters, including elution conditions, pH, ionic strength, sorbent amount, adsorption and desorption times, and shaking speed, were systematically optimized. The developed SPE-UHPLC-MS/MS method achieved recoveries of 92.7–102.9% across dates, tomatoes, grapes, and apples, with excellent linearity (R2 = 0.9985–0.9997), LODs of 0.010–0.051 ng/g, and LOQs of 0.031–0.155 ng/g. These results demonstrate the suitability of COF-RC as an efficient sorbent for trace-level carbamate determination in food and highlight its potential for food safety monitoring.
