Description:
The effluents containing the discarded water from the textile industry are graded as
one of the foremost pollutants in all industrial sectors. The wide varieties of dyes,
which is susceptible to the possibility of carcinogens or mutagens, and it will be
harmful to entire ecosystem. The titanium dioxide, one of the foremost heterogeneous
semiconductor photocatalysts, has been acknowledged for the wide applications
in hydrogen production from water splitting and degradation of organic and inorganic
pollutants since last few decades. The present work is successively advanced
for the removal of methylene blue from the seawater. The work was carried under
natural sunlight with the presence of C/TiO2 and Cu–C/TiO2. The photocatalytic
removal experiment was carried out with different catalyst dosages (0.25–1.25 g/L),
different initial concentrations from 5 to 30 μM and at different pH values (3–9).
The highest removal rate was found at the optimum condition of pH 8 and 1 g/L. At
the optimum condition, 100% efficiency was achieved under natural sunlight. The
kinetic studies reveal the pseudo-first-order kinetics and half-life time comparison
proves the enhanced visible light harvesting of Cu–C/TiO2.
