Photocatalyctic Removing of Safranin-O By Nickel- Doped Titanium Dioxide Nanoparticle -Coated Clinopetilolite Natural Zeolite

Doping Some kinds of metals by photocatalysts and increasing their surfaces lead to improve their photocatalyctic activities.in this study, Nickel dopant and Iranian natural Zeolite are used to increase the efficiency of titanium dioxide nanoparticle in order to photocatalyctic removing of Azonium components from water.
Clinopetilolite zeolite Surface coatedby Ni- doped Titanium with 4 of 0.17, 2,9 ratio Ni/TiO2 , and pure TiO2 through sol-gel method was made by analytical methods of automated X-ray splashing(XRD), Scanning Electronic microscope (SEM) and induced coupled plasma(ICP) have been examined. Then the efficiency level of Photocatalctic activities of different ratios of dopant Nickel under ultra-violet ray (UV) in 25,50 mg/L concentrations, water solved Safranin (phenazine compound) has been investigated.
Findings: In the present study, TiO2 nanoparticles in both the anatase and rutile phases were obtained via the sol-gel method with the ratios of 86.33%, (34.44 nm particle size) and 13.67% (18 nm particle size) and were then coated on Iranian natural clinoptilolite zeolite. According to this findings, Nickel dopant samples have exhibited the better efficiency in comparison with samples without Nickel. In addition, adding the Nickel caused Anatase phase frequency reduction of samples and increasing the photocatalytic reaction race. N9TC sample with ability of 93% and 79% Photocatalyctic removing power for Saffron with 25 and 50 mg/L concentrations ,have shown the best efficiency through different Photocatalyctic samples
The use of Iranian clinoptilolite as a substrate is the most cost-effective way to increase the photocatalytic activity, also adding Nickel to Titanium dioxide increases the efficiency of Safranin removing ability as a Phenazine Compound. Increasing the Ni/TiO2 ratio to 9% causes improving of photocatalytic power of samples in comparing of samples with only pure Titanium dioxide.
