Experimental and Computational Investigations of Decolourization of Rhodamine B in Aqueous Solution
(2017)
The aim of the study was comparatively to investigate decolourization of Rhodamine B (RhB) in aqueous solution using photocatalytic and ultrasonic processes. Also, computational investigations of RhB0 and RhB+- compounds ...
Influence of some crosslinkers on the swelling of acrylamide-crotonic acid hydrogels
(1997)
Acrylamide-crotonic acid hydrogels in the form of rods are prepared by $\gamma$-irradiation of quaternary mixtures of acrylamide-crotonic acid-crosslinker-water with 2.6 and 5.2 kGy $\gamma$-rays. The influence of the ...
Validation of the Charge Equalization Principles during the Formation of Small Molecules
(2017)
The electrophilicity equalization principle recently presented by Chattaraj and his co-workers has been criticized by Szentpaly. In the present report, we found that the charge equalization process for small molecule is ...
Kinetic spectrophotometric determination of trace copper(II) ions by their catalytic effect on the reduction of brilliant cresyl blue by ascorbic acid
(2011)
In the present study, a novel catalytic-kinetic spectrophotometric method was developed for the determination of trace amounts of copper. It is based on the catalytic effect of Cu(II) on the reduction of brilliant cresyl ...
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 ...
