A rapid and sensitive method has been developed for the determination of benzaldehyde, a toxic oxidation product of the widely used preservative and co-solvent benzyl alcohol in injectable formulations of non-steroidal anti-inflammatory drugs, diclofenac, vitamin B-complex and Voltaren injection solutions by using dispersive liquid-liquid microextraction followed by gas chromatography. This met...

the task specific ionic liquid (tsil), tricaprylmethylammonium thiosalicylate ([a336][ts]),was synthesized, characterized and subsequently used as extraction solvent in dispersive liquid-liquidmicroextraction (dllme) technique. the tsil-dllme method followed by inductively coupled plasmaatomicemission spectrometry (icp-aes) was applied to determination of trace mercury (hg) and cadmium(cd) in a...

Background and Objectives: Heterocyclic aromatic amines (HAAs) are carcinogenic and mutagenic substances, which are formed during the heating process of proteinaceous foods such as meat and meat products. The extraction of these compounds from the complex matrix of meat products was carried out by microwave assisted pre-extraction and a precise, rapid and high sensitive microextraction method. ...

Suitable to perform liquidliquid dispersion of controlled mean droplet

In the present research, salting out and vortex assisted dispersive liquid–liquid microextraction based on solidification of floating organic drop microextraction (SO-VADLLME-SFODME)  for the extraction and determination of phenol and chlorophenols in water samples followed by HPLC have been studied through a novel, simple, low-cost, selectable and environment friendly (so called green) method....

In the proposed method, carbon tetrachloride and ethanol were used as extraction and dispersive solvents. Several factors that may be affected on the extraction process, such as extraction solvent, disperser solvent, the volume of extraction and disperser solvent, pH of the aqueous solution and extraction time were optimized. Under the optimal conditions, linearity was maintained between 1.0 ng...

6 In this study, a total of 370 rice samples collected from six provinces in China were 7 surveyed for the presence of aflatoxins (AFs) and ochratoxin A (OTA) using 8 dispersive liquid-liquid microextraction coupled to liquid chromatography with 9 fluorescence detection. The results obtained in this survey showed that 63.5% 10 (235/370) and 4.9% (18/370) of rice samples contained detectable amo...
