A rotating packed bed with blade packings was used to produce zinc oxide (ZnO) nanoparticles by precipitation. Precursors were firstly produced in a continuous liquid-liquid reaction of zinc chloride (ZnCl2) with sodium hydroxide (NaOH). The effects of the concentrations of ZnCl2 and NaOH, the flow rates of aqueous ZnCl2 and NaOH, and the rotational speed on the size of the precursors were studied...
Zinc oxide (ZnO) nanoparticles can be prepared by the precipitation method in a rotating packed bed (RPB). In this work, precursors were firstly prepared in a continuous mode using the liquid-liquid reaction of zinc chloride (ZnCl2) and sodium hydroxide (NaOH). The effects of the molar ratio of ZnCl2 to NaOH, the flow rates of aqueous ZnCl2 and NaOH, the rotational speed, and the concentrations of...
