a comprehensive study pertaining to the emulsion liquid membrane (elm) extraction process to enrich dilute aqueous solutions of silver salt is presented. the study has highlighted the importance and influence of membrane composition for maximizing the extraction of ag+ ions. the liquid membrane was made up of cyanex-302 as an extractant and the industrial solvent mainly consists of paraffinic a...

In this study, extraction of amoxicillin (AMOX) ions from aqueous solution by liquid-liquid extraction (LLE) was investigated. The LLE process by response surface methodology (RSM) was carried out based on central composite design (CCD). The organic phase consisted of extractant and toluene as diluent. In this process, triethylamine (TEA), di-2-ethylhexyl phosphoric acid and mono-2-ethylhexyl p...

Spectrometric techniques for the analysis of trace cadmium have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, such as electrochemical deposition, precipitation, coprecipitation, solid phase extraction, liquid-liquid extraction (LLE) and cloud point...

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...

Process engineers can be faced with the task of understanding and optimizing the performance of an existing liquid-liquid extraction (extraction) column. Often times, an extraction column has been operating many years, and the performance is not well understood by the personnel responsible for its operation. Since this technology is not treated comprehensively during most under-graduate Chemica...

Purpose: To develop a sensitive and validated reverse phase-high performance liquid chromatographic (RP-HPLC) method for quantification of olanzapine in micro-sample of rat plasma using UV detection. Methods: A single oral dose of olanzapine (7 mg/kg) was given to overnight fasted rats (n = 6). Rat plasma samples containing the drug were extracted by liquid-liquid extraction using a combination...
