Development of a New Methodology for Determination of Vitamin B9 at Trace Levels by Ultrasonic-Assisted Cloud Point Extraction Prior to HPLC

Ulusoy, Halil Ibrahim; Acidereli, Hilal; Ulusoy, Songul; Erdogan, Selim (SPRINGER, 2017)

A new analytic methodology based on ultrasonic-assisted cloud point extraction coupled with high-performance liquid chromatography (UA-CPE-HPLC) was developed and successfully applied to determine vitamin B9 in food samples. ...
Indirect Determination of Free, Total, and Reversibly Bound Sulfite in Selected Beverages by Spectrophotometry Using Ultrasonic-Assisted Cloud Point Extraction as a Preconcentration Step

Altunay N.; Gürkan R.; Sertakan K. (2015)

A new indirect ultrasonic-assisted cloud point extraction (UA-CPE) method has been developed for the determination of trace sulfite species by means of spectrophotometry. The method is based on either directly imide–bisulfite ...
Separation/preconcentration of ultra-trace levels of inorganic Sb and Se from different sample matrices by charge transfer sensitized ion-pairing using ultrasonic-assisted cloud point extraction prior to their speciation and determination by hydride generation AAS

Altunay N.; Gürkan R. (2016)

In the existing study, a new, simple and low cost process for separation/preconcentration of ultra-trace level of inorganic Sb and Se from natural waters, beverages and foods using ultrasonic-assisted cloud point extraction ...
