The order of magnitude of the heats of adsorption of Ca2+ salts indicates the occurrence of a chemical reaction of hardness salts with negatively charged fibers of the fabric. Addition of a complexing agent reduces the concentration of calcium salts in solution. It was shown that the adsorption of nonionic surfactant and anionic surfactant mixtures on fabrics is higher than that for individual surfactants. The presence of a binary chelator in solution increases the adsorption ability and detergency of the compositions in hard water.</p></abstract><trans-abstract xml:lang="ru"><p>Изучена адсорбция компонентов моющего раствора на чистой и загрязненной хлопчатобумажной ткани в воде различной жесткости. Порядок величин теплот адсорбции солей Са2+ свидетельствует о протекании химической реакции солей жесткости с отрицательно заряженными группами волокон ткани. Введение комплексообразователей уменьшает концентрацию кальциевых солей в растворе. Показано, что величина адсорбции смеси анионных и неионных ПАВ на ткани выше, чем для индивидуальных ПАВ. Присутствие бинарного комплексообразователя повышает адсорбционную и моющую способность композиций в жесткой воде.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>адсорбция</kwd><kwd>анионные ПАВ</kwd><kwd>неионное ПАВ</kwd><kwd>загрязненная ткань</kwd><kwd>соли жесткости</kwd><kwd>смеси поверностно-активных веществ</kwd><kwd>комплексообразователи</kwd><kwd>моющая способность.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adsorption</kwd><kwd>anionic surfactants</kwd><kwd>nonionic surfactants</kwd><kwd>soiled fabric</kwd><kwd>hardness salts</kwd><kwd>surfactant mixture</kwd><kwd>chelating agents</kwd><kwd>detergency</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">Филиппенков В.М. // Прикладная аналит.</mixed-citation><mixed-citation xml:lang="en">Филиппенков В.М. // Прикладная аналит.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">химия. 2013.
