best predictor-
To determine influence of technical conditions on product diameter, the influences of concentrations, molar ratio, reaction temperature and time on average size were investigated by means of uniform design. the results of experiments indicated that product diameter was mostly influenced by reaction temperature, followed by molar ratio of reactant, concentration of reactants, and reaction time. the optimum conditions were c ( co ( no3 ) 2 6h2o ) = 0. 35mol / l, n ( co ( nh2 ) 2 ) : n ( co ( no3 ) 2 6h2o ) = 3. 53 : 1, reaction temperature 94 and reaction time 3. 53h
以產物的平均粒徑( nm )為優化指標,選擇硝酸鈷濃度、反應物摩爾比、反應溫度和反應時間四個因素,運用均勻試驗設計技術進行3 ~ 5 1 ~ 3因素優化試驗,發現反應溫度對產物的粒徑影響最大,其次分別為反應物摩爾比、硝酸鈷濃度以及反應時間,並確定最佳反應條件為:硝酸鈷濃度0 . 35mol l ,反應物摩爾比為3 . 53 : 1 ,反應溫度94 ,反應時間3 . 53h ,預報值粒徑y _ 1 = 19 . 57nm ,在此優化條件下制得的納米co _ 3o _ 4平均粒徑為22nm 。
