Abstract: In order to get of catalyst inexpensive and effective application for photodegradation, TiO2 powder which were prepared by the electrodeposition method simple and inexpensive and using surfactants such as (Glycerin (GLY), Polyvinyl Alcohol (PVA), Poly (N-Vinylpyrrolidone) (PVP)) that help the growth and nucleation of suspended particles. These particles were distinguished by (Atomic Force Microscopy (AFM), X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), EDS and High Resolution Transmission Electron Microscope (HRTEM), these particle was obtained reached to the about 40 nm, in order to demonstrate the photodegradation efficiency of the titanium dioxide in the removal of the organic Malachite Green oxalate (MG) dye, the catalyst was used in both cases the standard Titanium Oxide (TiO2, 80 vol% anatase +20 vol% rutile) from (US research nanomaterials, Inc) and prepared TiO2 calcination at 700°C to converted from anatas phase to TiO2 anatase/rutile phase and the parameters such as amount of catalyst, concentration of dye, pH of dye sol and temperature were calculated. Pseudo first order reactions according to, the Langmuir-Hinshelwood can be obtained from results photocatalytic reactions. Parameters such as: Energy activation (Ea), Enthalpy of activation (ΔH0), entropy of activation (ΔS0) and free energy of activation (ΔG0) were calculated the activation energy equal to (56.73±1) and (37.49±1) kJ/mol for (MG) dye inpresence TiO2 NPs in tow case standard and prepared, respectively.
