    Ecological sorbent based on saponite mineral from Ukrainian clay-field
    (Publishing House of Lviv Polytechnic National University, 2012) Spivak, Victoria; Astrelin, Igor; Tolstopalova, Natalia; Atamaniuk, Iryna
    The physico-chemical, structural and adsorption characteristics of saponite mineral from Tashkivske clay-field and their changes under the influence of acid, thermal and ultrasonic activation were investigated. Stabilization mechanism of the colloidal system “saponite-water” under the influence of stabilizing agents was studied. Moreover, the effectiveness of saponite multipurpose usage was proved by experiments. Досліджено фізико-хімічні та структурно-адсорбційні характеристики сапонітового мінералу Ташківського родовища та їх зміну під впливом кислотного, термічного та ультразвукового активування. Вивчено механізм впливу стабілізуючих агентів на стійкість колоїдної системи “сапоніт-вода”. Експериментально доведено ефективність використання сапоніту для отримання сорбентів багатогалузевого призначення.
