Abstract

U radu je ispitano uklanjanje zagađivala iz efluenta proizvodnje mehanički

mljevene drvenjače sorpcijom na prirodne i sintetske alumosilikate. Rabljeni su

klinoptilolitni tuf, mordenitni tuf, sintetski zeolit A, sintetski zeolit tipa mordenita i

bentonit. Uzorci alumosilikata su različito modificirani. Od alumosilikata najveću

učinkovitost sorpcije polutanata iz otpadne vode pokazao je uzorak kiselo

modificiranog sintetskog zeolita tipa mordenita (učinkovitost sorpcije je 47%).

Od uzoraka klinoptilolitnog tufa modificiranih ugljikohidratima najbolji se

pokazao uzorak modificiran glukozom (učinkovitost sorpcije je 11%).

Karbonizacijom ugljikohidrata na površini tufa dodatno se povećava učinkovitost

sorpcije. Povećanje je vrlo slabo zbog malog udjela ugljika na površini tufa.

Učinkovitost sorpcije od 11% dobivena je i s željezovim (II) sulfatom

modificiranim tufom. Aktivni ugljen i heksadeciltrimetilamonijevim ionima

modificirani uzorci klinoptilolitnog tufa pokazuju sličnu učinkovitost sorpcije (~

30%).

Abstract (english)

The study analyzed how to remove contaminants from the effluent of

mechanically produced wood pulp with sorption on natural and synthetic

alumosilikate. There was used a clinoptilolite tuff, a tuff mordenit, a synthetic

zeolite A, a mordenite type of synthetic zeolite and bentonite. Samples of

aluminosilicate were variously modified. The highest efficiency of sorption of

pollutants from wastewater showed a sample of acid modified synthetic zeolitetype

mordenite (efficiency of sorption is 47%). The best carbohydrate modified

clinoptiolite tuf reveal the one with glucose (sorption efficiency is 11%).

Carbonization of carbohydrates on the surface of zeolites further increases the

efficiency of sorption. The increase was very low because of the small share of

carbon on the surface of the tuff. Sorption efficiency of 11% was obtained also

with iron (II) sulfate modified tuff. Activated carbon and samples of clinoptiolite

tuff modified with HDTMA ion show similar sorption efficiency (~ 30%).
