关键词： Polyester dendritic functionalized graphene oxide Pipette tip micro solid-phase extraction Venlafaxine Desvenlafaxine

摘要：

A novel adsorbent, second-generation polyester dendritic functionalized graphene oxide (PDG-2), was developed for pipette tip micro solid-phase extraction of venlafaxine and desvenlafaxine from urine. Leveraging the facile modification properties of graphene oxide and the controlled synthesis capabilities of dendritic materials, PDG-2 exhibited a rough surface and numerous active groups with adsorption capacities of desvenlafaxine and venlafaxine up to 187 mg g-1 and 230 mg g-1. Method validation confirmed excellent linearity, low detection limits, high precision, and accurate recovery. Compared with commercial adsorbents, PDG-2 outperformed HLB and MCX and matched the performance of C18 with a much smaller amount.Copyright © 2024 Elsevier B.V. All rights reserved.
