Determination of trace amounts of iodide by an inhibition kinetic spectrophotometric method
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 ... -
Kinetic spectrophotometric determination of trace copper(II) ions by their catalytic effect on the reduction of brilliant cresyl blue by ascorbic acid
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 ... -
Misel İyileştirilmiş Katalitik Kinetik Spektrofotometri Aracılığıyla İçecek Örneklerinde Eser Düzeylerdeki Nitritin Belirlenmesi

A simple and efficient approach for preconcentration of some heavy metals incosmetic products before their determinations by ame atomic absorptionspectrometry
Nail Altunay; Ramazan Gürkan (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 ... -
Surfactant-sensitized spectrophotometric determination of Hg(II) in water samples using 2-(2-thiazolylazo)- p-cresol as ligand and cetylpyridinium chloride as cationic surfactant
A new, reliable, surfactant-sensitized method is described for the spectrophotometric determination of total and dissolved inorganic mercury at trace levels. The method is based on the ternary complex formation of Hg(II) ...
