In this research, photocatalytic degradation of DisperseFlor Pink BGdye were examined in the presence of zinc ferritenanoparticles at non-buffer pHs under 400 W high pressure mercury lamp under aerobic conditions at room temperature. The effects of UV light, buffer and non-buffer pHs, irradiation time and nano-powder zinc oxide were studied.The photochemical degradation of dye was found to behave as a first order reaction. Kinetic investigation of photodegradation of Disperse Flor Pink BG dye, showed that the reaction obey from improved Langmuir-Hinshelwood (L-H) model.Using this model,observed rate constant and Langmuir-Hinshelwood adsorbtion constant were determined.
