Предельная адсорбция, адсорбционная емкость, константа адсорбции максимальны для вариантов поочередной адсорбции анионного полиэлектролита на подложке из катионного полиэлектролита. Высокая адсорбционная емкость и энергия взаимодействия полимеров с поверхностью и между собой приводит к улучшению флокуляции и увеличению скорости осаждения солевой дисперсии каолина в 1,3–1,5 раза.</p></abstract><trans-abstract xml:lang="en"><p>As a result of the study of the effect of acrylamide copolymers on the stability of the kaolin salt dispersion, it was shown that the aggregation of solid phase particles and the deposition rate of flocs increases when polymers with different adsorption activity are alternately dosed to a disperse system. The adsorption limit, adsorption capacity and adsorption constant are at maximum for alternate adsorption of anionic polyelectrolyte on a cationic polyelectrolyte layer. High adsorption capacity and interaction energy of polymers with the surface and with each other leads to an improvement in flocculation and to the increase in the deposition rate of the kaolin-salt dispersion by 1.3–1.5 times.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>акриламидные сополомеры</kwd><kwd>солевая дисперсия</kwd><kwd>адсорбция</kwd><kwd>устойчивость</kwd><kwd>каолин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>аcrylamide copolymers</kwd><kwd>salt dispersion</kwd><kwd>adsorption</kwd><kwd>stability</kwd><kwd>kaolin</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Мягченков, В.
