Organic dyes used by textile industry to colour the fabric to enhance their
appearance and market value are a big concern for environment and marine ecosystems.
Millions of tons of such dyes are discharged into our water resources every year. This
study presents a simple, low-cost, and highly efﬁcient photocatalyst based on iron oxide
nanoparticles. The photocatalytic properties of iron oxide nanoparticles were system-
atically investigated by measuring the degradation of Eosin Y and Rhodamine B dyes.
This study show that the catalytic properties of iron oxide nanoparticles can be further
enhanced by simultaneous exposure to light and ultrasound. We observed an almost 1.5-
and 4-folds enhancement in catalytic degradation of Eosin Y and Rhodamine B,
respectively under sonophotocatalytic degradation conditions. The degradation of the
model dyes was observed to follow ﬁrst order degradation kinetics.
