A new, sensitive and fast dispersive liquid-liquid microextraction (DLLME) coupled with micro-solid phase extraction (μ-SPE) was developed for determination of zearalenone (ZEN) in wheat samples. The DLLME was performed using acetonitrile/water (80:20 v/v) as the disperser solvent and 1-octanol as the extracting solvent.  The acetonitrile/water (80:20 v/v) solvent was also used to extract ZEN f...

Liquid phase micro-extraction (LPME) of metals has showed its potential for sample preparation in environmental analysis. In particular, the incorporation ionic liquids to LPME (IL-LPME) gotten increasing interest due their unique properties as organic salts liquid at room temperature. last years, IL-LPME evolved more efficient and selective extraction methods thanks development task specific l...

Ionic liquid ions sources (ILIS) extract ions from room temperature molten salts, or ionic liquids. Ion extraction is achieved by stressing the ionic liquid into a Taylor cone structure, formed on the apex of micro-sized, nanostructured tips known as emitters. These ion sources can be used in applications such as ILIS electrospray propulsion for multi-scale spacecraft and materials processing a...

the aim of this study was to develop an easy analytical method for determining flam prop-m- iso propyl residues in honey by high performance liquid chromatography with uv detection (hplc/uv) for routine analysis. chromatographic separation was carried out at room temperature on a zorbax eclipse xdb- c18, 100 å pore size, 5 μm particle size (300 mm × 3 mm i.d.) column using a mobile phase of met...

the effects and influences of various parameters upon the efficiency and the overall volumetric mass transfer coefficients are important subjects to be studied in most liquid-liquid extraction processes. one of these important parameters is surface active agent (surfactant). in this paper, in order to study the effect of sodium dodecyl sulfate (sds) concentration on the efficiency and the avera...

background & aim: according to the increase in diseases such as diabetes and obesity, using of saccharose alternatives for producing of low-calorie and sugar-free alternatives, are taken into consideration of researchers and industrialists. among them, steviosidewith the 300 times more sweetness than saccharose has special place, due to is a natural. the aim of this study is optimizing of stevi...

recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. end-product reutilization, low product concentration, large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2, 3-butanediol production. extraction can successfully be used f...
