MOFs were also applied for matrix solid-phase dispersion extraction (MSPDE). MSPDE methods based on several MOFs such as Gd(DPA)(HDPA), Zn(BDC)(H20)2, and (Lao,9Euo,i)2(DPA)3(H20)3 were developed for the extraction and determination of pesticide residues in medicinal plant and vegetables. The MOFs gave better or similar performance for the pesticides tested than conventional neutral alumina or commercial phase Cjg-bonded silica. [Pg.444]
