Abstract—The photocatalytic degradation of Methylene Blue (MB) dye has been investigated by locally available Magnetite with H₂O₂. Parameters such as Magnetite dosage, concentration of dye pH effect, light intensity and oxidizing agent (H₂O₂) were used to study the degradation of MB. The degradation rates were found to be strongly influenced by all the above parameters. The Magnetite/ H₂O₂/UV process proved to be capable of decolorizing Methylene Blue.

Index Terms—Photocatalytic degradation, magnetite, oxidizing agent, methylene blue.
