Ultrasound-Assisted Low-Density Solvent-Based Dispersive Liquid-Liquid Microextraction Coupled to Spectrophotometry for the Determination of Low Levels of Histamine in Fish and Meat Products
In this study, a new low-density solvent-based dispersive liquid-liquid microextraction strategy coupled to spectrophotometry has been developed for the determination of the trace levels of histamine in fish and meat ...
Ion pair vortex assisted-ionic liquid based dispersive liquid-liquid microextraction for selective separation and preconcentration of 4-methylimidazole from caramel colour drinks and foodstuffs prior to its spectrophotometric determination
(ELSEVIER SCIENCE BV, 2019)
In the study, a simple, fast, easy to use, cost-effective and green analytical method was developed for the selective extraction and determination of 4-methylimidazole (4-MeI) from caramel colored drinks and foods by using ...
A Simple and Green Microextraction Procedure for Extraction of Morin in Food and Beverages Using Ionic Liquid
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 ...
Use of 2-Hydrazinobenzothiazole-Modified Copolymer(s) as Potential Chelating Agent for Sensitive and Selective Determination of Low Levels of Mercury in Seafood by Ultrasound-Assisted Cloud-Point Extraction Combined with Spectrophotometry
(Humana Press Inc., 2019)
In this study, a new method was developed for the pre-concentration of trace mercury from seafood samples prior to analysis by spectrophotometry. The method is based on the complexation between 2-hydrazinobenzothiazole ...
