A Simple and Green Microextraction Procedure for Extraction of Morin in Food and Beverages Using Ionic Liquid
(SPRINGER, 2019)
In this study, a practical and rapid microextraction procedure based on ionic liquid (IL) was proposed for the spectrophotometric determination of morin (2-(2,4-dihydroxyphenyl)-3,5,7-trihydroxychromen-4-one) in foods and ...
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 ...
Extraction, Preconcentration, and Quantification of Low Levels of Free Formaldehyde from Some Beverage Matrices by Combination of Ultrasound-Assisted-Cloud Point Extraction with Spectrophotometry
(Springer New York LLC, 2017)
In the present study, due to use of formaldehyde (FA) as a food additive as well as its endogenous and natural occurrence in aquatic products, a new preconcentration method for the quantification of free formaldehyde (FA) ...
