The new method of purification of the industrial waste waters
Abstract: The main problem in the all existing electrofloatation methods of cleaning is the increase of the alkalization space near the cathode that leads to formation of the salts sediments on the cathode as a result of passing of the electric current through the water environment. The salts so tightly cover cathode’s surface that can cause the total curtailment of the process of electrofloatation. This can be explained by the fact …

Chromatographic Techniques with Biological Applications
Abstract: Chromatography is kind of a number of purification performances distinct as differential relocation from a slight preliminary zone. Electrophoresis is another member of this group. In this case, the driving force is an electric field which exerts different forces on solutes of different ionic charge. The resistive force is the viscosity of the nonflowing solvent. The combination of these forces yields ion mobilities peculiar to each solute. Chromatography technique for …
