Abstract. This work presents a process for phenol removal comprising
a reaction step in which phenol is polymerized in the presence of an enzyme
horseradish peroxidase. A crude preparation from horseradish roots was
used as a low purity source of the enzyme. The technical feasibility of
the process was studied using 1 to 10 mM synthetic phenol solutions. Experimental
results showed the potential of the proposed technique. A phenol conversion
higher than 90% was observed at the polymerization process.

UKLANJANJE FENOLA IZ INDUSTRIJSKIH OTPADNIH
VODA PEROKSIDAZOM IZ RENA (Cochlearia armoracia L)
Ovaj rad prikazuje proces uklanjanja fenola iz sintetičkih otpadnih voda
koji uključuje reakciju polimerizacije fenola u prisustvu enzima peroksidaze
iz rena (Cochlearia armoracia L). Sirovi preparat dobijen iz korena rena
je korišten kao izvor enzima niske čistoće. Tehničke mogućnosti ovog procesa
su proučavane upotrebom sintetičkog rastvora fenola koncentracije 1-10
mM. Eksperimentalni rezultati pokazuju potencijal predložene tehnike. Konverzija
fenola veća od 90% je dobijena u ovom procesu polimerizacije.
Ključne reči: Otpadne vode, uklanjanje fenola, peroksidaza iz
