Surfactant-sensitized spectrophotometric determination of Hg(II) in water samples using 2-(2-thiazolylazo)- p-cresol as ligand and cetylpyridinium chloride as cationic surfactant
(2012)
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) ...
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 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 ...
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 ...
