Determination of Parabens in Beverage Samples by Dispersive Liquid–Liquid Microextraction Based on Solidification of Floating Organic Droplet

Preconcentration of acrylamide with dispersive liquid-liquid microextraction based on solidification of floating organic drop prior to determination by HPLC

A novel, rapid, simple and sensitive dispersive liquid-liquid microextraction method based on the solidification of floating organic drop (DLLME-SFO) combined with high performance liquid chromatography-ultra violet detection (HPLC-UV) was used to determine acrylamide in potato chips. The derivation of the acrylamide happened in the presence of KBr, KBrO3, H2SO4. Based on studies, 1-undecanol w...

Dispersive Liquid-Liquid Microextraction Based on Solidification of Floating Organic Drop Combined with Flame Atomic Absorption Spectrometry for Preconcentration and Determination of Thallium(III) in Water Samples

Dispersive Liquid-Liquid MicroExtraction technique based on Solidification of a Floating Organic drop (DLLME-SFO) combined with flame atomic absorption spectrometry was developed for determination of thallium in water sample. An appropriate mixture of acetone and 1-undecanol was rapidly injected into an aqueous sample containing TlCl4- which forms an ion pair with bril...

Dispersive liquid–liquid microextraction based on solidification of floating organic drop combined with flame atomic absorption spectrometry for determination trace amount of cobalt in water samples

An efficient, rapid, simple, and highly selective dispersive liquid–liquid microextraction basedon solidification of floating organic drop (DLLME-SFOD), combined with flame atomicabsorption spectrometry was developed for preconcentration and determination of trace amountsof cobalt in water samples. In this method, an appropriate mixture of acetone and1-undecanol was injected rapidly into the aq...

dispersive liquid- liquid microextraction based on solidification of floating organic droplet followed by spectofluorimetry for determination of carvedilol in human plasma

Development of dispersive liquid–liquid microextraction solidofied floating organic drop (DLLME SFOD) method for determination of cadmium in biological samples

Introduction: Todays, exposure to heavy metals is happened by being produced in various environmental, industrial processes. The production of metals finally results in air pollution as well as contamination in the food chain. There are harmful effects of heavy metals such as cadmium on different organs. Therefore, this study aimed to identify and quantify cadmium in biological samples using DL...
