The investigation of synthesis of the spinel Co1-xCdxFe2O4 photocatalyst by co-precipitation method at various proportions of (x = 0.2:0.8, 0.5:0.5, 0.8:0.2) and calcinations at temperature 600 ºC for 3 h. The synthesized powder was characterized by X-ray diffraction, FT-IR, UV-visible spectroscopy, SEM, EDS, AFM and HPLC. The photocatalytic activity was estimated under high pressure mercury lamp OSRAM (125) watts for degradation phenol red solution at the wavelength of λmax 432 nm. The conclusion demonstrated that (0.5:0.5) rate at 600 ºC has high action than other proportion at various temperature. After this examination, a few measures, for example, better of mass for the catalyst, initial of concentration for spinel Co1-xCdxFe2O4, effect of pH and effect of temperature. The X-ray and electron microscopy studies showed an average size of the granules prepared for the composite in this manner (18.16-39.64). The electrical characteristics (L.C.R) were additionally examined for all the spinels. Cadmium alone was an electrical insulator but by adding cobalt with iron it turned into a semiconductor of an electric current.
