Бұл зерттеу Ақтөбе ферроқорытпа зауытынан алынған XShP-02 хромшпинелі шламының (бай бөлігі) мұнай өңдеу зауыттарының ағынынан фенолды сорбент ретінде жою әлеуетін зерттейді. Шлам 70 °C-та 1 М NaOH ерітіндісімен сілтілік модификациядан өтіп, кейін 450 °C-та кальцинацияланды. Физико-химиялық қасиеттері XRF, SEM, ИҚ спектроскопия және TGA/DSC әдістерімен сипатталды. Лангмюр және Редлих–Петерсен модельдері адсорбциялық тепе-теңдікті ең жақсы сипаттайды (R² = 1,000). Ең жоғары адсорбциялық сыйымдылық 36,00 мг/г; 0,30 г/100 мл оңтайлы доза фенолдың 96 %-ын жоюды қамтамасыз етеді. ΔG° = -5,97 кДж/моль адсорбцияның спонтанды физикалық сипатын және сорбентті қайта өңдеу мүмкіндігін растайды.
