[ 1 ] - Trace Analysis of Niflumic Acid in Milk and Human Plasma by Ion-pair-based Vortex Assisted Dispersive Liquid-liquid Microextraction Combined with UV-Vis Spectrophotometry
A simple, accurate and fast vortex-assisted dispersive liquid-liquid microextraction procedure has been developed for the extractive spectrophotometric determination of niflumic acid in biological samples. The method is based on the formation of an ion association complex between niflumic acid and methylene blue. The resulting ion-pair was extracted into dichloromethane and its absorbance was m...
