摘要
用均相沉淀法制备出了纳米氧化镍,所选取的原料和沉淀剂价廉易得,沉淀效果好,工艺路线简单易行。探讨了原料配比,沉淀剂滴加速率,pH值和反应时间对氧化镍生成量的影响。用正交试验法确定了较优的工艺条件,即原料配比为4∶1,沉淀剂滴加速率为1mL·min-1,反应时间为60min,溶液的pH值为5.4。
A nano-nickel oxide is prepared by method of homogeneous sedimentation. The materials selected and precipitating agent are low priced and easily obtained and the effect is better .The technological process is simple and easy. This paper inquires into the influences of materials ratio and precipitating agent rate and pH value and reacting time to the yield of nano-nickel oxide.By using orthogonal test method optimum technological conditions are determined: materials ratio is 4∶1,precipitating agent rate is 1 mL/min,reacting time is 60 min ,and pH value is 5.4.
