Statistical Parameters Effects on Photocatalytic Degradation of Rhodamine 6G Dye with Hexagonal Zinc Oxide Nanorods Synthesized via Solution Process

摘要

Hexagonal-shaped zinc oxide nanorods (HNRs) were synthesized via a wet chemical solution process at low temperature in short refluxing time. The structural and morphological properties of the obtained products were characterized by x-ray diffraction pattern and field emission scanning electron microscopy. The photocatalytic degradation process significantly shows enhanced activity of ZnO-HNRs under UV-Vis light in presence of rhodamine 6G dye (RhB). The effective concentration of ZnO-HNRs shows degradation process of RhB dye and was investigated via standard analytical techniques, optimized and validated by statistical analytical parameters. The statistical constraints give necessary information for establishing analytical procedures to ensure the quality and purity of the results. The absorption spectra were recorded at maximum absorbance lambda (max) 470 nm, 520 nm, and 550 nm for ZnO-HNRs, RhB and ZnO-HNRs-RhB, respectively. Satisfactory data were obtained from UV-Vis spectroscopy, providing more reliable values against many factual variable factors such as concentration, volume, pH, time and temperature, etc.
