Abstract:
The kinetics of oxidative decomposition of fuchsine dye
using selected Cu-doped lead zirconate (Cu-doped-PLZ) was
studied carefully in an aqueous solution in the presence of
H2O2 under condition of pseudo-first
order reaction. The catalyst was prepared by conventional
solid state reaction technique, the structural and micro-structural
properties of the catalyst were characterized well by XRD
and SEM respectively. Many of the kinetic parameters were
investigated in this article , results obtained indicated
that, the rate of oxidative degradation of acid fuchsine dye
was found to be pH-dependent. The mechanism was proposed and
the activation parameters were calculated.
Keywords: Cu- doped-PLZ , Kinetics, SE-microscopy,
X-ray Diffraction, oxidative,
Degradation, Fuchsine dye.
