First, Schiff base iminopyridine ligands has been prepared by the condensation between primaryamines, different substituted anilines and active carbonyl group of pyridine carboxaldehyde, thenthe complexes [diiodo (3-ethylphenyl) pyridine-2-yl methylene amine] mercury(II), complex a,[dibromo (2,5-dimethylphenyl) pyridine-2-yl methylene amine] mercury(II) complex b, and[dinitrato bis-(2,6-dimethy...

Polypyrrole multi-walled carbon nanotube composite layers were used to modify the gold layer to measure heavy metal ions using the surface plasmon resonance technique. The new sensor was fabricated to detect trace amounts of mercury (Hg), lead (Pb), and iron (Fe) ions. In the present research, the sensitivity of a polypyrrole multi-walled carbon nanotube composite layer and a polypyrrole layer ...

The article discusses own studies’ materials of anthropogenic mercury migration in the “soil− plant − surface water- water body bottom sediments” system on example technogenically mercury-polluted territory northern industrial zone Pavlodar city Kazakhstan. distribution processes soil at a depth up to two meters, and sediments Irtysh River, as well “Pamyat’ Azieva” soft spring wheat variety gro...

The metal-induced intramolecular cyclization reaction of an azo dye was exploited for the colorimetric detection of mercury ions in water. The molecular probe 3 responds selectively to nM-level Hg(II) ions in neutral aqueous solutions.

The influence of halide and isothiocyanate ions of the reduction wave of aquopentamminecobalt(‡V) and aquopentamminechromium(‡V) ions at the dropping mercury electrode has been studied by the measurements of current-potential and current-time curves. The cobalt (‡V) complex ion gives a kinetic-controlled reduction wave at more positive potentials than that of the reduction of cobalt(‡V) to coba...

The research situation of the application carbon quantum dot fluorescent materials to detection metal ions, including current status and preface recent years, development trends are summarized. ions is highlighted, iron copper mercury lead silver ions. Finally, problems prospects for detecting discussed.

The poorly known mechanism of inhibition of cholinesterases by inorganic mercury (HgCl2) has been studied with a view to using these enzymes as biomarkers or as biological components of biosensors to survey polluted areas. The inhibition of a variety of cholinesterases by HgCl2 was investigated by kinetic studies, X-ray crystallography, and dynamic light scattering. Our results show that when a...

Cross-linked chitosan was synthesized with chitosan and ethylene glycol diglycidyl ether. The adsorption behavior of trace amounts of metal ions on the cross-linked chitosan was systematically examined by packing it in a mini-column, passing a metal solution through it and measuring metal ions in the effluent by ICP-MS. The cross-linked chitosan adsorbed mercury and precious metals (Pd, Pt, and...

[1] We have analyzed measurements of planetary ions near Mercury made by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) Fast Imaging Plasma Spectrometer (FIPS) over the first three Mercury years of orbital observations (25 March 2011 through 31 December 2011). We determined the composition and spatial distributions of the most abundant species in the regions sampl...
