A new method of UA_CPE coupled with spectrophotometry for the faster and cost-effective detection of proline in fruit juice, honey, and wine
(ELSEVIER SCI LTD, 2018)
The study developed a new method for proline detection in honey, wine and fruit juice using ultrasound assisted-cloud point extraction (UA-CPE) and spectrophotometry. Initially, a quaternary complex was built, containing ...
Development of vortex-assisted ionic liquid-dispersive microextraction methodology for vanillin monitoring in food products using ultravioletvisible spectrophotometry
(ELSEVIER SCIENCE BV, 2018)
The research deals with development of a new methodology for preconcentration and determination of vanillin in food products using vortex-assisted ionic liquid-dispersive microextraction (VAILDME) followed by ultraviolet-visible ...
Utility of ultrasound assisted-cloud point extraction and spectophotometry as a preconcentration and determination tool for the sensitive quantification of mercury species in fish samples
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)
The current study reports, for the first time, the development of a new analytical method employing ultrasound assisted-cloud point extraction (UA-CPE) for the extraction of CH3Hg+ and Hg2+ species from fish samples. ...
Preconcentration and determination of trace vanadium(V) in beverages by combination of ultrasound assisted-cloud point extraction with spectrophotometry
(Slovensko Kemijsko Drustvo, 2018)
A novel ultrasound assisted-cloud point extraction method was developed for preconcentration and determination of V(V) in beverage samples. After complexation by pyrogallol in presence of safranin T at pH 6.0, V(V) ions ...
Preconcentration and indirect quantification of trace nitrite, nitrate and total nitrite in selected beverage and milk samples using ion-pairing cloud-point extraction with acridine orange
(Academic Press Inc., 2018)
A new indirect preconcentration method was developed for micellar-sensitive detection of trace nitrite as analyte by spectrophotometry. It is based on selective ion-pairing complex formation of triiodide ion, I3 ? with ...
