an ultrasound-assisted surfactant-enhanced emulsification microextra- ction (uaseme) coupled with high performance liquid chromatography-diode array detection has been developed for the extraction and determination of thiopental in serum and urine samples. a simple microextraction method based on emulsification of organic extraction solvent in aqueous sample using an ionic surfactant and withou...
In this article cloud-point extraction (CPE) was used with chelating agent to extract uranium from aqueous solutions. The methodology used is based on the formation of metal complexes soluble in a micellar phase of surfactant. The metal ions complexes are then extracted into the surfactant-rich phase at a temperature above the cloud-point temperature. The effect of type of surfactants and ligan...
Background: Sesame oil has anti-candidiasis therapeutic effects. Due to hydrophobic property of oils, their solubility in aqueous media is low which causes their low absorption and impact on the reduction of microbe compactness in the body. The aim of the present study was preparation of a mixture containing sesame oil and honey based on microemulsion form. Materials and Methods: An experimenta...
The strategy of adding hydrophobic compounds to bio-based films (usually based on hydrophilic matrices), forming containing emulsions, is a technique that has been used improve some physical properties (such as reducing water solubility and vapor permeability) / or impart properties, such antioxidant antimicrobial effects by carrying active components would otherwise be insoluble in matrices. A...
The valorisation of biomass-derived platform chemicals via catalytic hydrogenation is an eco-friendly tool which allows us to recover bio-based building blocks and produce fine with high industrial appeal. In the present study, a novel surfactant-type triazolyl-thioether ligand was prepared, showing excellent activity in presence bis(1,5-cyclooctadiene)diiridium(I) dichloride [Ir(COD)Cl]2 for f...
in this study, a bacterial species which could remove lead from wastewater was isolated from lead contaminated soil prepared in the laboratory. based on the biochemical and morphological characterization the bacteria were identified as brevundimonas vesicularis. the biosorption potentiel of powdered dry biomass of b. vesicularis was investigated by batch adsorption experiments. it was found tha...
