摘要
以氯化镍为镍盐,以碳酸氢铵为沉淀剂,用液相化学沉淀法制备纳米NiO。主要研究沉淀过程中三种不同加料方式下镍离子浓度变化规律,着重研究顺加方式下镍离子浓度、溶液pH值随时间变化、Z电位和团聚粒径随pH值变化规律,进而找出最佳工艺参数。
NiO nano- particles are synthesized via Liquid Chemical Precipitation using NiCl2 · 6H2O as nickel salts and NH4 HCO3 as precipitation agents. The research studies the thickness change rule of Ni^2+ in three different ways of appending material in Precipitation, focusing on the change rule of thickness of Ni^2+, the pH with the passage of time, Zata potential and the aggregate size with different pH in the way of appending more and more material. On the basis of this, the best technical parameter is determined.
