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 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 ...
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 ...
