Graphene oxide framework: An adsorbent for solid phase extraction of phenylurea herbicides from water and celery samples.
1,4-Phenyldiboronic acid (1,4-PDBA) linked graphene oxide framework (GOF) was prepared via an one-step, catalyst-free and hydrothermal route. To evaluate its adsorption performance, the prepared GOF was served as an adsorbent for solid phase extraction of phenylurea herbicides (PUHs) from water and celery samples prior to their determination by high performance liquid chromatography. The results indicated that GOF exhibited excellent adsorption capacity for the target PUHs. Under the optimum conditions, the method showed high recoveries ranged from 86.0% to 112.0%, low relative standard deviations (<5.4%) and low limits of detection ranged from 0.01 to 0.02ngmL-1for water and 0.025-0.050ngg-1for celery sample, respectively. These results indicated the great application potential of GOF in the enrichment of organic pollutants from different matrix samples.
