Aim of work - development of theoretical bases of water purification by method of activated bubble-film extraction with the use of special activators of process - surface-active cationic polyelectrolytes. The experimental researches were carried out by the methods of surface chemistry using the laboratory models of bubble-film water-purifiers, which were created in the process of the previous research work. During the work the influence of structure of polyelectrilytes molecules on their ability to form surface film on water - air interface was investigated. The process of interaction of polyelectrolytes molecules with endogenous surface-active substances and with surfaсe-inactive water contamonants was analysed, the formation of complexes with the specified substances was investigated. The degree of extraction from polluted water of iron and arsenic compounds by methods ordinary and activated bubble-film extraction was analysed. The bactericidic action of these special reagents was studied with respect on such parameters "Total microbe number " also "Coli-index". Application area - water treating, public health services, food-processing industry. Product Description popup.authors popup.nrat_date 2020-04-02 Close
