加料方式对纳米氧化镍收率影响的研究

Study on the Effect of Charging Modes on the Output of Nanoparticle NiO

在常温下,以N iC l2.6H2O为原料,(NH4)2CO3为沉淀剂,采用液相沉淀法制备纳米N iO。在相同反应条件下采用顺加、逆加、并加三种加料方式,实验结果表明逆加方式得到产物的收率最高。

At ambient temperature, Nano - NiO is synthesized by NiCI2 . 6H2O and （NH4）2CO3 via liquid chemicat precipitation method. The result of the experiments in which three charging modes are carried out under the same reaction condition shows that converse mode has the highest output.
