Abstract
In the work, optimization of operating parameters of methylene blue photodegradation was carried out. Zinc oxide nanopowder electrochemically synthesized under asymmetric pulse alternating current in BaCl2 solution was used as a photocatalyst. The physicochemical properties of the synthesized zinc oxide nanopowder were studied by a number of instrumental methods (X-ray Diffraction, transmission electron microscopy, energy-dispersive X-ray spectroscopy). Optimal technological parameters such as photocatalyst loading, UV light intensity, and pH which are characterized by the maximum rate of methylene blue photodegradation were determined.
Keywords: zinc oxide, pulse alternating current, photocatalysis, water treatment, methylene blue
