Abstract :
Plant materials have been found useful in decontamination of water polluted with phenolic
compounds. The detoxification effect is due to peroxidases contained in plant tissue. Enzyme
mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and
its removal from the aqueous phase. A synthetic wastewater buffered at pH = 7.4 containing 0.9
mM phenol was treated in this research with cut Raphanus sativus root and its juice. Cut
Raphanus or Raphanus juice were added separately as enzyme source to phenol solution in
buffer and in tap water in two series of experiments. The reaction was initiated by the addition of
hydrogen peroxide. After three hours stirring the phenol content of the mixtures was determined.
More than 90% of phenol was removed in both cases
