Abstract

Diatomite silica doped iron nanoparticle thermally calcination at 600 °C “ DMF3X6 ” composite as catalyst for heterogeneous photocatalysis of vat green 03 indanthren and characterized in this study.The Diatomite silica doped iron nanoparticle thermally calcination at 600 °C called “ DMF3X6 ” was made through surface modification treatment including NaOH deposition on raw diatomite with thermally calcination .In NaOH treatment, surface of Diatomite silica doped iron nanoparticle thermally calcination at 600 °C “ DMF3X6 ” was partially dissolved in NaOH with thermally calcination at 600 °C by means of x-ray fluorescence ( XRF ), x-ray diffraction ( XRD ), attenuated reflection-Fourier transform infrared ( ATR-FTIR ), scanning electron microscopy ( SEM ), energy dispersive x-ray ( EDX ) ,thermogravimetric analysis ( TGA ) , differential scanning calorimetry (DSC ) and UV–visible diffuse reflectance spectroscopy ( DRS ) .The surface area of Diatomite silica doped iron nanoparticle thermally calcination at 600 °C “ DMF3X6 ” is 218.2 m2/g .The bad gap of DMF3X6 was Eg = 1.15 eV by UV-visible DRS technique .The surface modification also increased the point of zero charge (pHPZC ) values to 6 for Diatomite silica doped iron nanoparticle thermally calcination at 600 °C “ DMF3X6 ” .The vat green 03 indanthren textile dye degradation has pH dependency, the better result is at pH =10 with colour remove about 92 %.The photodecolourisation rate follows pseudo-first order kinetic with to respect to the dye concentration.
