| Abstract: | A
novel Fe encapsulated montmorillonite K10 clay has been prepared by solid state
dispersion method and characterized by FT-IR, SEM-EDS, ICP-AES and BET surface
area measurements. XRD analysis suggests that iron in the catalyst exists as
FeOOH. ICP-AES analysis shows increase in Fe(III) concentration from 35 to 457
ppm on immobilization of Fe on montmorillonite K10 clay. EDS analysis of SEM
images also confirm the presence of Fe in the catalyst. The catalyst has been
applied for photodegradation of Acid Yellow 17 in the presence of H2O2
under UV light. Effect of pH on mineralization of the dye has been
studied in detail. The initial pH influences not only the photocatalytic
activity of the catalyst but also the Fe leaching from the catalyst. Unlike
homo-Fenton catalysts, the proposed catalyst exhibits good activity and
stability even at neutral pH 7 (75 % at 60 min irradiation). Further,
lowest leaching of Fe(III) at pH 7 makes the catalyst suitable for dye
wastewater treatment at neutral pH. |
