This study involved the treatment of textile wastewater contaminated with direct blue
15 dye (DB15) using a heterogeneous photo-Fenton-like process. Bimetallic iron/copper
nanoparticles loaded on bentonite clay were used as heterogeneous catalysts and
prepared via liquid-phase reduction method using eucalyptus leaves extract (E-Fe/Cu@BNPs).
Characterization methods were applied to resultant particles (NPs), including SEM,
BET, and FTIR techniques. The prepared NPs were found with porous and spherical
shapes with a specific surface area of particles was 28.589 m2/g. The effect of main
parameters on the photo-Fenton-like degradation of DB15 was investigated through
batch and continuous fixed-bed systems. In batch mode, pH, H2O2 dosage, DB15
