A Simple and Green Microextraction Procedure for Extraction of Morin in Food and Beverages Using Ionic Liquid
Altunay, Nail; Elik, Adil; Gurkan, Ramazan (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 ... -
Simultaneous determination of antimony and boron in beverage and dairy products by flame atomic absorption spectrometry after separation and pre-concentration by cloud-point extraction
Altunay, Nail; Gurkan, Ramazan (TAYLOR & FRANCIS LTD, 2016)A new cloud-point extraction (CPE) method was developed for the pre-concentration and simultaneous determination of Sb(III) and B(III) by flame atomic absorption spectrometry (FAAS). The method was based on complexation ... -
Ultrasound assisted extraction and spectrophotometric determination of trace selenium in water, food and vegetable samples
Altunay, Nail; Gurkan, Ramazan; Gunes, Murat (ROYAL SOC CHEMISTRY, 2016)In the present study, a new ultrasound assisted extraction (UAE) method was developed for preconcentration of selenite, Se(IV), from sample matrices prior to analysis. The method is based on complex formation between ... -
