The purity of the final product reached 95% through ion-exchange chromatography on DEAE Sepharose Fast Flow chromatography and Delta-Pak TM C18 purification after optimizing the chromatographic conditions. The capacity of purification process was 50mg/circle. The total yield was 36%. The technology is simple and reliable, and can be scaled up easily.展开更多

Phases, particle sizes and morphology of the prepared nanocrystallite were characterized by Powder X-ray diffraction (XRD) and transmission electron microscopy(TEM). The results showed that the crystallite product had an average size about 30 nm. The effects of a series of reaction conditions on the synthesis of Zn(Oxin)2·2H2O (Zinc 8-quinolinolate) by solid state reaction were studied.展开更多
