ABSTRACT / SAŽETAK:
U ovom radu ispitana je razgradnja lindana (100 µg/L) primenom biouglja dobijenog pirolizom biomase drveta (0,2 g/L) kao katalizatora za aktivaciju kalijum persulfata (PS). Eksperimenti su sprovedeni pri različitim koncentracijama PS (0,5–9,0 mM) i pH 7,0 ± 0,2. Optimalna doza PS iznosila je 3,0 mM, pri čemu je postignuta efikasnost razgradnje veća od 90%. Dalje povećanje koncentracije PS nije značajno poboljšalo razgradnju. Najveći deo reakcije odvija se u prvih nekoliko sati, a ravnoteža se uspostavlja nakon 4 sata. Dobijeni rezultati potvrđuju da biougalj efikasno aktivira PS i ukazuju na njegov potencijal za tretman voda kontaminiranih organskim mikropolutantima.
