    Thermodynamic studies of bromphenol blue removal from water using solvent sublation
    (Publishing House of Lviv Polytechnic National University, 2016) Obushenko, Tetiana; Tolstopalova, Natalia; Kulesha, Olga; Astrelin, Igor
    The investigation of thermodynamic peculiarities of bromphenol blue (BB) elimination from aqueous solutions using solvent sublation technique has been carried out. Thermodynamic properties of acid dye (BB) interaction with cationic surfactant cetylpyridinium chloride (CPC), applying Kharash method and HyperСube HyperСhem Professional software were studied. It was proven that dye-surfactant ion complex formation is a spontaneous process and does not require any external forces for its run. Проведені дослідження термодинамічних особливостей вилучення бромфенолового синього (БС) з водних розчинів, використовуючи технологію флотоекстракції. Вивчено термодинамічні характеристики взаємодії кислотного барвника (БС) з катіонною поверхнево-активною речовиною (ПАР) – хлоридом цетилпіридинію (ЦПХ), використовуючи метод Караша та програмне середовище HyperСube HyperСhem Professional. Доведено, що формування йонного комплексу барвник-ПАР є самочинним процесом і не потребує жодних зовнішніх сил для його перебігу.
