Установлено, что процесс адсорбции усиливается при уменьшении рН раствора, но является достаточно эффективным и в нейтральных средах. Эффективность протекания адсорбции в слабо-кислых средах позволяет решить проблему коррозионных потерь стального оборудования за счет снижения концентрации минеральной кислоты при снятии карбонатных отложений.</p></abstract><trans-abstract xml:lang="en"><p>Adsorption of EDTA on calcite depending on the EDTA concentration and pH of the solution is investigated. It is established that adsorption enhances when decreasing pH of the solution being rather efficiency in neutral media as well. The adsorption efficiency is weakly acidic media makes it possible to solve a problem of corrosion loss of steel equipment due to lowering the concentration of mineral acid when removing carbonate scales.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбонатные отложения</kwd><kwd>очистка поверхности</kwd><kwd>адсорбция</kwd><kwd>динатриевая соль этилендиаминтетрауксусной кислоты (трилон Б</kwd><kwd>ЭДТА)</kwd><kwd>карбонат кальция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbonate scales</kwd><kwd>cleaning of surfaces</kwd><kwd>adsorption</kwd><kwd>ethylenediaminetetraacetic acid disodium salt (Trilon B</kwd><kwd>EDTA)</kwd><kwd>calcium carbonate</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">Artamonova I.V., Gorichev I.G., Godunov E.B.
