Optimization of vortex-assisted ionic liquid dispersive liquid–liquid microextraction by experimental design prior to hydride generation atomic absorption spectrometry for determination of selenium species in food, beverage and water samples
(Elsevier, 2021)
We applied novel vortex-assisted ionic liquid dispersive liquid-liquid microextraction (VA-IL-DLLME) method to preconcentration and extraction of Se(IV) ions from water, beverage and food samples. The method was optimized ...
Ultrasound-assisted supramolecular solvent dispersive liquid-liquid microextraction for preconcentration and determination of Cr (VI) in waters and total chromium in beverages and vegetables.
(Elsevier, 2021)
Simple, sensitive, selective and green ultrasound assisted supramolecular solvent dispersive liquid-liquid microextraction (UA–SUPRAS-DLLME) method was developed for preconcentration and determination of chromium ions in ...
Experimental and theoretical investigation for the spectrophotometric determination of thiabendazole in fruit samples
(Elsevier, 2021)
A simple, green, and effective vortex-assisted dispersive liquid–liquid microextraction method was developed for separation, preconcentration and spectrophotometric determination of thiabendazole in fruit samples. This ...
Feasibility of supramolecular nanosized solvent based microsyringe-assisted liquid-phase microextraction for preconcentration and separation of Vitamin B12 from infant formula, food supplement, and dairy products: Spectrophotometric analysis and chemometric optimization
(Elsevier, 2021)
Here, a novel cheap and green analytical method based on supramolecular nanosized solvent based microsyringe-assisted liquid phase microextraction (SS MA LPME) was developed and validated for preconcentration and separation ...
A new analytical approach for preconcentration, separation and determination of Pb(II) and Cd(II) in real samples using a new adsorbent: Synthesis, characterization and application
