A cloud point extraction (CPE) process was described for the separation and spectrophotometric analysis of Fe(III) in different water samples blood as chelating agent. The complexation reaction between Zincon elaborated at pH 5.0 using acetate buffer complex quantitatively recovered a mixed micelle system composed cethyltri methyl ammonium bromide (CTAB) Triton X-114. This carried out room temp...

The main idea in this research used quercetin (QT) as a stabilizing agent to prepare CuO nanoparticle (NPs). QT is pigment which exists from plants, fruits, and some medicines. It contains numerous hydroxyl groups, works complexing self-assembly agent. prepared CuO-NPs were characterized by fourier transformed infrared (FT-IR), X-ray diffraction (XRD), scanning transmission electron microscopy ...

In this project by the use of cilicagel as Sorbent for preconcentration of traces of Cu and Zn considered by Solid Phase Extraction prior to determination by flame Atomic Absorption Spectroscopy (FAAS). In this method 4,2 Pyridilazo resorsinol (PAR) as a complexing agent For copper and zinc ion after adsorbed in cilicagel and after that eluted by 5 ml of nitric Acid (3M). Some effective Paramet...

The objective of this study was to produce well-dispersed nanosized yttria tetragonally stabilized zirconia (Y-TZP) powder in aqueous suspension. The Y-TZP powder was produced by precipitation from homogeneous solution at 2001C under hydrothermal conditions. A homogeneous solution was created through the use of a complexing agent, which subsequently could be used in a dispersion scheme develope...

A novel highly sensitive optical NO2-selective sensor was developed using phthalocyaninato-iron(II) as a selective complexing agent. In order to solubilize the ironII+phthalocyanine and to obtain the monomer species, a N-donor ligand was used as a solvent. The membrane solution was deposited onto a novel aluminum oxide/hydroxide nanoporous material by a spin-coating technique. The chemical reac...

Lithographically fabricated iridium-based mercury microelectrode arrays are shown to be very suitable for adsorptive stripping measurements of trace nickel in the presence of the dimethylgloxime complexing agent. Variables affecting the response have been assessed and optimized. The sensor optimization has resulted in a favorable and highly stable response, with good linearity and precision (RS...
