The potable water is one of the most valuable products containing mineral and organic substances of different types necessary for a man. However alongside with useful substances it usually contains various poisonous products (chlorine, heavy metal salts, nitrates, pesticides, surfactants and oil products) which makes its consumption quite dangerous for a man.
One of the modern ways of the populat Continue Reading »

At last time visual tests have been distributed for determination ions metals in deferent ecological and technologic objects.
Various analytical needs are caused the necessary of creation new selective, sensitive test-reagents.
We have considered a series of the solid carriers, such as the transcarpathian mordenite , silica gel and silipor modified by the complex- Continue Reading »

Taking into account that the rejection of a gaseous NO in atmosphere is extraordinarily toxic, we did an attempt to estimate the nitrogen monoxide action on the surface of the several amorphous metallic alloys (АМA). It could be used for prognostication of catalytic action of these alloys in processes of finally oxidation or NO reduct Continue Reading »

The photocatalytic purifying is one of the perspective methods in the process of which reagents adsorption on the catalyse surface proceeds at the same time with organic moleculs destruction.
The sorption part study in the photocatalytic destruction processes of the Tetradecylpyridinium Cloride (TDPC Continue Reading »
THE STUDIES ON THE SELECTIVE ADSORPTION OF SOME METAL IONS ON THE MODIFIED ION EXCHANGERS

Development and broader application of the ion exchange methods proved possible when modern organic and inorganic ion-exchangers of suitably chosen physicochemical properties were produced and used. Of many well known ion exchangers only a few types are produced on the commercial scale now. There are selective ion exchangers of various type with the follow Continue Reading »
Prediction of monolayer adsorption equilibrium characteristics on the basis of similarity theory

Nowadays one of the main adsorption theory problems is the correct description of the monolayer adsorption equilibrium characteristics; the most important of which are the adsorption isotherm and the Henry coefficient. Despite the fact that both molecular-statistic and phenomenological models have been obtained for the theoretical adsorption isotherms and the Henry coefficient, it is still very difficult to accoun Continue Reading »
