photo catalytic property of zno and mn-zno nanoparticles in removal of cibacet turquoise blue g from aquatic solution
Authors
abstract
zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. also, photo catalytic removal of cibacen turquoise blue g dye from aqueous solution by using nano scale zno and mn-zno powders under uv light irradiation was studied. the effect of initial dye concentrations and dosage of photo catalysts, were investigated in the photo destructive process. this is 57% of dye degraded by 0.02 mg of zno in 70 minutes. the degradation rate increase to 84% in the presence of 0.02 mg of mn-zno in the same time.

In this work firstly ZnO nanoparticles were synthesized via a simple precipitation method. At the second step titanium dioxide and silicon dioxide shell were synthesized on the core. For preparation ZnO-TiO2-SiO2 the sol product was calcinated at 500 ºC for 2h. Properties of the product were examined by X-raydiffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform inf...

Zn1 - x Mn x O nanoparticles have been synthesized by hydrothermal technique. The doping concentration of Mn can reach up to 9 at% without precipitation or secondary phase, confirmed by electron spin resonance (ESR) and synchrotron X-ray diffraction (XRD). Room-temperature ferromagnetism is observed in the as-prepared nanoparticles. However, the room-temperature ferromagnetism disappears after ...

Due to its ability in chemical oxidation of contaminants, iron nanoparticle is a material of choice to remove lead ions from aquatic solutions. In this study a reduction method in solution phase was applied to synthesize thenanoparticles. Afterwards, the size of the synthesized particles were confirmed by Scanning Electron Microscopy. It is worth noting that th...
