AB  - Various organic pollutants are discharged into the water from chemical, textile and
pharmaceutical industries every day. The photocatalytic wastewater treatment is an efficient,
cheap and eco-friendly process for the removal of organic toxic dyes, such as methylene blue,
which is one of the most common toxic dyes in wastewater. Photocatalysts ZnCr mixed
oxides were synthesized and thermally treated at 500 and 900 °C. Their efficiency in
photocatalytic degradation of methylene blue and the influence of the reaction parameters
were studied. High photocatalytic activity of both samples was observed, where the complete
decolorization (100%) and partial decolorization (45%) of the aqueous solution of methylene
blue were achieved after 6 hours for ZnCr 900 and ZnCr 500, respectively. In order to
determine the influence of the pH on the photocatalytic effieciency, the photodegradation
reactions were conducted using better performing photocatalyst at different pH values,
measuring the photodegradation efficiency at the same time intervals. The optimal pH
resulting in the most efficient photodegradation for ZnCr 900 photocatalyst was observed at
pH 12, which could be explained by the correlation with different textural and structural
properties of photocatalysts. The results showed that the obtained ZnCr mixed oxides are
highly efficient in the methylene blue photodegradation and have a great potential for the
application in the photocatalytic wastewater treatment processes.
