Abstract :
In this research, new catalyst prepared by supporting
CoFe2O4 on copper slag (CS) and characterization
of this catalyst was done with using scanning electron
microscopy image, energy-dispersive X-ray spectroscopy,
BET surface area, and X-ray diffraction patterns.
UV ? H2O2 processes by CoFe2O4/CS as a photocatalyst
was used for degradation of 2-nitrophenol (2NP) as a
pollutant in water. Response surface methodology in the
Basis of a three-variable Box–Behnken design was applied
to determine the effect of pH values (4, 7 and 10), concentration
of 2-nitrophenol (10, 20 and 30 ppm), and
concentration of H2O2 (30, 60 and 90 ppm) on the levels of
response and optimized these operational parameters. The
optimal conditions were determined as pH = 10, concentration
of 2-nitrophenol = 10 ppm, and concentration of
H2O2 = 90 ppm. Degradation efficiency in optimal condition
was 96.55%.
