Determination of Bisphenol A in Beverage Samples Using Ultrasonic- Extraction and Atomic Absorption Spectrometry
(2017)
In this work, a simple and versatile ultrasound-assisted extraction (UAE) procedure, which provides high separation efficiency for bisphenol A (BPA), was developed for its indirect determination in beverages in contact ...
Determination of manganese and iron in magmatic rocks after ultrasonic leaching by flame AAS
(2002)
An alternative sample preparation method has been developed for destructive analysis of magmatic rock sample. The method simply included the crushing, HF treatment and 1% HCl leaching steps of the rock samples under ...
Palladium-catalysed Suzuki{Miyaura cross-coupling with imidazolylidene ligandssubstituted by crowded resorcinarenyl and calixarenyl units
(2015)
TwoN-heterocyclic carbene (NHC) palladium complexes of formula [PdBr2(NHC)(pyridine)] in which thecarbenic ring is anked by sterically crowded cavitand substituents were prepared from appropriate imidazolium saltsbearing ...
Determination of calcium, magnesium and aluminium in magmatic rocks after ultrasonic leaching by flame AAS
(2002)
A method of ultrasonic leaching has been developed for the destructive analysis of magmatic rock $samples^1$. This method was applied to determine three new elements, Ca, Mg and Al, in magmatic rock samples. The accuracy ...
Determination of trace amounts of iodide by an inhibition kinetic spectrophotometric method
(2004)
In this study, the reaction between Co(III)-EDTA and hypophosphite ion, catalyzed by Pd(II), was chosen as the indicator reaction. The inhibition kinetics of this catalytic reaction were investigated in the presence of ...
Some Heavy Metal Contents of Various Slaughtered Cattle
(2017)
As a result of environmental pollution and food chain, heavy metals may accumulate in human or animal bodies. Toxic metals cause inhibition on chemical and enzyme reactions in cells. Therefore, a negative situation forms ...
A simple and efficient approach for preconcentration of some heavy metals incosmetic products before their determinations by ame atomic absorptionspectrometry
(2016)
In the current study, a simple and efficient analytical method for preconcentration and determination ofCd(II), Pb(II), and Sn(II) in some cosmetic samples, using ultrasonic assisted-cloud point extraction and ame ...
DETERMINATION OF THERMAL PROPERTIES OF A82 ORGANIC PHASE CHANGE MATERIAL EMBEDDED WITH DIFFERENT TYPE NANOPARTICLES
(2018)
The low thermal conductivities of organic phase-change materials must be increased so that they can be used effectively in practice. In this work, it is aimed to enhance the thermal conductivity of PCM by adding nanoparticles ...
