Web9 Apr 2024 · After a 30 min extraction, the MIP thin film was washed with 5.0 mL of ultrapure water to remove residual sample matrix components. The MPA was desorbed from the MIP devices using 700 μL of 90% acetonitrile, 9.9% water, and 0.1% formic acid in a conical vial vortex mixed at 1000 rpm for 2 min. Following desorption, MIP thin films were … Web25 Feb 2015 · In this study, metal–organic framework (MOF)-199 was in situ grown on the surface of stainless steel mesh by a facile one-step hydrothermal synthesis strategy. A piece of the MOF-199-coated film was used as adsorbent in thin-film extraction. With octahedral shape, accessible macropores, and high surface area-to-volume, the MOF-199 coating …
