Abstract

Abstract: By using zinc nitrate and hydrogen sulfide as source materials, nanometer zinc sulfide was synthesized by a high
gravity method in a rotating packed bed. The effect of aging time on product sizes was investigated and 48h was chosen. Well-dispersed
nanometer zinc sulfide particles with a sphalerite crystal phase were prepared. The crystal structure, optical properties, size and morphology
of the product were also characterized by XRD, UV-Vis spectrophotometer and TEM. The results show that the average particle size of ZnS obtained is about
30nm and the conversion rate is 97.5 percent.

Key words: high gravity, rotating packed bed, nano-ZnS, preparation
