Vortex-Assisted Inverted Dispersive Liquid-Liquid Microextraction of Naproxen from Human Plasma and Its Determination by High-Performance Liquid Chromatography
Extraction and determination of naproxen from human plasma were performed using Vortex-Assisted Inverted Dispersive Liquid-Liquid MicroExtraction (VA−IDLLME) and High-Performance Liquid Chromatography (HPLC). The parameters affecting extraction recovery such as type and volume of extraction and disperser solvents, pH of sample solution, stirring rate, extraction time and salt addition were ...
متن کاملTrace 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...
متن کاملUse of Temperature-controlled Ionic Liquid-assisted Dispersive Liquid-Liquid Microextraction Method for the Detection of Amoxicillin, Cloxacillin and Erythromycin Residues in Cow Milk using High Performance Liquid Chromatography
Background and Objectives: Different types of antibiotics are used indiscriminately in animal husbandry for the growth and treatment of livestock, which cause accumulation of antibiotic residues in livestock products such as milk. Long-term consumption of milk contaminated with antibiotic residues above the permissible limits is harmful to human health, causing antibiotic resistance problems. T...
متن کاملApplication and Optimization of Dispersive Liquid-liquid Microextraction Coupled with High-performance Liquid Chromatography for Sensitive Determination of Furfural and Hydroxymethyl Furfural in Jarred and Canned Baby-foods
Background and Objectives: Furfural (F) and hydroxymethyl furfural (HMF) are cyclic aldehydes, which are formed during the heat processing of foods. These chemical contaminants have received much attention due to their suspected health hazards and heat damage indicators. The aim of the present study was extraction and determination of F and HMF in baby-foods using dispersive liquid-liquid micro...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
