Abstract
The parameters affecting the perticipation reaction for the production of dyspersium tungstate nanoparticles were optimized using the taguchi robust design. The parameters studied were the concentrations of dyspersium and tungstate solution, as well as the flow rate of the cation solution and temperature of the reactor, and the outcome under study was the dimensions of the percipitated nanoparticles. Analysis of variance (ANOVA) of the results proved that the flowrate of adding the cation solution (FZ) and the concentration of the solutions of both ions considerablly affect the outcome of the reaction. The synthesized dyspersium tungstate nanoparticles prepared under the optimized factors wereevaluated using X-ray diffraction (XRD), scanning electron microscopy (SEM), FT-IR and UV–Vis spectroscopy techniques. Furthermore, the as-synthsized dyspersium tungstate nanoparticles were used as efficient photocatalyst for the photocatalytic degradation of methylene blue under ultraviolet light.
