Abstract:Metal ion (
/oxidant) and UV light catalyzed (UV/oxidant) mineralization and biodetoxification of Ponceau Xylidine (PX) was undertaken in this study. Hydrogen peroxide (HP) and ammonium persulphate (APS) were employed as oxidants and
and
as metal ion catalysts. Although highest mineralization in
/APS and UV/HP systems was exhibited at pH 1 (63.09 %) and 3 (64.83 %), respectively, lowest was shown by
/oxidant systems at any pH. The Fenton process achieved mineralization of ≈48.50 % within the pH range of … Show more
