    Adsorption of heavy metals ions from liquid media by palygorskite
    (Publishing House of Lviv Polytechnic National University, 2015) Melnyk, L.; Bessarab, O.; Matko, S.; Malyovanyy, М.
    The process of heavy metals adsorption by natural mineral palygorskite from wastewater and food (apple juice) has been investigated. The purification processes of copper, cadmium, lead, mercury and zinc have been studied. The rational technological parameters of these processes have been determined. The mechanism for heavy metals adsorbtion from juice by palygorskite has been defined. Досліджено процес адсорбції важких металів природним мінералом палигорськітом із стічних вод та харчових продуктів (яблучного соку). Досліджені процеси очищення від йонів міді, кадмію, свинцю, ртуті, цинку та визна- чено раціональні технологічні параметри цього процесу. Встановлено механізм сорбції важких металів із соку палигорськітом.
