Preparation of Polypyrrole Modified Filter Paper and Its Application in the Detection of Benzimidazole Drugs in Honey
摘要
Abstract
Polypyrrole-modified cellulose extraction filter paper was synthesized from dissolving pulp via in-situ polymerization,yielding a cost-efficient,environmentally sustainable,and flexible material.This filter paper was employed as a solid-phase extraction medium in conjunction with HPLC-MS/MS for the extraction and quantification of seven benzimidazole compounds in honey.Method validation using honey samples spiked at three concentration levels(10,50,and 100 μg/kg)showed recoveries ranging from 51.4％to 101％,with standard deviations below 10.2％.The method achieved detection limits(LODs)between 2.19×10-2 μg/kg and 5.82×10-2 μg/kg and quantification limits(LOQs)from 7.29×10-2 μg/kg to 1.94×10-1 μg/kg.The extraction efficiency was found to be on par with that of commercial SPE cartridges.关键词
