Abstract: 
Експериментально досліджено адсорбцію йонів Cu2+ та Fe2+, звичайних важких металів, що знаходяться в промислових стічних водах, геополімером на основі золи виносу. Встановлено, що адсорбція кожного йона відбувається за реакцією псевдодругого порядку. Доведено, що ізотерма адсорбції йонів Cu2+ та Fe2+ відповідає моделі Ленгмюра. Визначено, що моношарова адсорбційна здатність становила приблизно 53,76 мг/г та 52,63 мг/г для йонів Cu2+ та Fe2+, відповідно.
