development of homogeneous liquid-liquid microextraction via flotation assistance method for determination of benzene, toluene, xylene and styrene in water samples
this study propose a new analytical protocol for the determination of benzene, xylene, toluene and styrene in water samples using homogeneous liquid-liquid microextraction via flotation assistance (hllme-fa) technique followed by gas chromatography-mass spectrometry (gc-ms). in this research, a special extraction cell was designed to facilitate collection of the low-density solvent extraction. ...
متن کاملHomogeneous Liquid-Liquid Microextraction via Flotation Assistance Method as a Sensitive and Efficient Sample Preparation Method for Determination of Diazinon in Water Samples
Homogeneous liquidliquid microextraction; Flotation assistance; Diazinon; Water samples ABSTRACT: In the present study a sensitive method for extraction of diazinon in water samples was developed using homogeneous liquid-liquid microextraction via flotation assistance (HLLMEFA). Toluene at microliter volume level was used as extraction solvent. The main advantages of method are high enrichment ...
متن کاملDevelopment of Homogeneous Liquid-Liquid Extraction in Combination with Dispersive Liquid-Liquid Microextraction Based on Deep Eutectic Solvents for the Extraction and Assessment of Phytosterols in Animal Cream Samples using Gas Chromatography Equipp
Background and Objectives: Food quality and safety control is an important part of the public health assessment of food adulteration has been a key issue in recent years. Cream is a product containing milk fat and is one of the most expensive and widely consumed edible fats, which is often targeted for cheating by mixing various vegetable oils with natural milk fats. A way to detect this type o...
متن کاملSpectrophotometric determination of molybdenum using surfactant-mediated liquid–liquid extraction
A new spectrophotometric method has been developed for determination of molybdenum using surfactantmediated liquid–liquid extraction. Molybdenum(V) obtained by ascorbic acid reduction in 2.5 M H2SO4 reacted spontaneously with thiocyanate and cetyl trimethyl ammonium bromide (CTAB), forming an intense orange yellow complex that was extracted quantitatively into 1,2-dichloroethane and absorbed at...
