Vortex assisted magnetic ionic liquid based dispersive liquid–liquid microextraction approach for determination of metribuzin in some plant samples with UV–Vis spectrophotometer
(26 July 20)
A vortex assisted magnetic ionic liquid based dispersive liquid–liquid microextraction (VA-MIL-DLLME)
approach was proposed using a tetrachloromanganate-based magnetic ionic liquid (MIL, as extraction solvent) for the ...
DETERMINATION OF THE BIOLOGICAL ACTIVITY OF Lavandula stoechas L.
(2022)
Lavandula stoechas is an aromatic plant belonging to the Lamiaceae family (Dob et al., 2006; Kaplan et al., 2019; Bilenler and Gökbulut, 2019). It is known that Lavandula stoechas plant, which is in the form
of a bush, ...
Application of levulinic acid-based natural deep eutectic solvents for extraction and determination of deltamethrin in food samples
(2022)
In the study, a fast and green natural deep eutectic solvent based ultrasound-assisted liquid liquid microextraction (NDES-UALLME) were proposed for the determination and extraction of deltamethrin in food samples using ...
Linear and nonlinear optical properties of a superlattice with periodically increased well width under electric and magnetic fields
(Micro and Nanostructures, 2022/6/1)
In this paper, we have studied the electronic and optical properties of GaAs/AlxGa1-xAs superlattice with periodically increased well width. Under effective mass approximation, the finite element method is used to obtain ...
Sensitive determination of Anastrozole and Letrozole in urine samples by novel magnetic nanoparticles containing tetraethylenepentamine (TEPA) prior to analysis by high-performance liquid chromatography-diode array detection
(Springer, 2022)
Magnetic solid-phase extraction coupled to high-performance liquid chromatography (HPLC)-diode array detection method has been developed for the sensitive analysis of Anastrozole (ANA) and Letrozole (LET) in human urine ...
Synthesis, characterization, and application of polyacrylamide/carmine polymer nanomaterial as an effective solid-phase material for ultrasonic-assisted solid-phase microextraction of aluminum and chromium in vegetable samples
(Springer, 2022)
Here, a new and inexpensive polymer nanomaterial consisting of polyacrylamide and carmine (PAM-CR) was synthesized to provide selective extraction of aluminum and chromium from vegetable samples prior to their determination ...
Application of cloud point extraction for residues of chloramphenicol and amoxicillin in milk samples by HPLC–DAD
(Springer, 2022)
A pre-concentration and sensitive determination method for residues of Chloramphenicol (CLP) and Amoxicillin (AMX)in milk samples were developed based on cloud point extraction (CPE) and HPLC–DAD analysis. CLP and AMX ...
New cobalt phthalocyanine–graphene oxide hybrid nanomaterial prepared by strong π–π interactions
(2022)
In this study, a novel hybrid nanomaterial was obtained by interaction of cobalt phthalocyanine (CoPc) derivative on the surface
of graphene oxide (GO) producing a CoPc-GO supermolecular system in which interaction is ...
Nutritional concentration values of field larkspur (Concalide regalis) consumed as purple mint in Sivas
(2022)
The Ranunculaceae family contain 50 to 60 genera and 2,500
species. Some plants belonging to this family are highly poisonous and
are used as herbal medicines or spices (Bruneton, 1999; Ipor and Oyen,
1999; Heywood et ...
