Lead isolation from its salt diluted solutions can be carried out by lead precipitation particles surface as slightly soluble hydroxide, hydrophobization of by appropriate surfactant (collector) and following hydrophobizated particles flotation. The information about the mechanism of surfactant interaction with lead hydroxide is necessary for efficient prognosis of surfactants action as flotation collect Continue Reading »

Designed in Institute of Sorption and Endoecology Problems amorphous granulated modified titanium and zirconium phosphates differ from crystalline types of phosphates. Due to the optimal size of granules and developed porosity they can be utilized in sorption columns with low hydrodynamic drag force, that un Continue Reading »

Production of metal oxide powders and sphere of their application have been expanding on the regular basis. The significant number of disperse oxides are used for obtaining composite materials with the required set of properties. Even distribution of particles of highly dispersed powders in disperse medium is among one of the problems that occur at producing such materials.
The issues of securing a homogenous coagulation structure of dispers Continue Reading »

Among numerous silica gels the wide-pore gels are especially useful as adsorbents because of their high degree of chemical purity, homogeneity and mechanical resistance. Water similarly as other liquids (n-butanol, benzene, n-octane) adsorbed on solid surfaces, especially on silica gel surfaces, induces the changes of physicoch Continue Reading »

In the removal of metal ions from dilute solutions, the most efficient and selective are the inorganic materials with adsorption ability essentially determined by ion-exchange and chemical interactions, in particular, the formation of complexes. Phosphates of alkali earth metals are efficient for the sorption of heavy metal ions. Among these phosphates, the hydroxyapatite Continue Reading »
