Spectra of sodium aluminate solutions MA Shu-hua(马淑花)1, 2, ZHENG Shi-li(郑诗礼)1, XU Hong-bin(徐红彬)1, ZHANG Yi(张 懿)1 1. Laboratory of Green Process and Engineering, Institute of Process Engineering... aluminate solutions were obtained in the sodium oxide concentration range from 59 to 409 g/L and the caustic ratio range from 1.5 to 4.0 to reveal the structure characteristics of them. It is found......
Adjustment on gibbsite and boehmite co-precipitation from supersaturated sodium aluminate solutions WANG Zhi(王 志)1, YANG Liu(杨 柳)1, 2, ZHANG Juan(张 娟)1, 2, GUO Zhan-cheng(郭占成)1, ZHANG Yi(张 懿)1 1... supersaturated sodium aluminate solutions simultaneously, and the competitive formation between Al(OH)3 and γ-AlOOH determines the main precipitate phases from pregnant liquor. Boehmite seeds, high......

aluminate because dissolution requires considerable time to reach equilibrium. Thus, the effect of duration on the concentration of lithium ion in sodium aluminate solutions was investigated (Figure 2... of lithium will be precipitated from solutions. Based on aforementioned data, the equilibrium concentration of lithium ion in sodium aluminate solution can reach over 1.2 g/L during digestion at high......
of additive on seeded precipitation rate of sodium aluminate solution The effects of propionic acid, ethamine and their mixture on the seeded precipitation rates of sodium aluminate solutions are shown... effects of α-alanine, propionic acid, ethamine and the mixture on the precipitation process of sodium aluminate solutions all become weak when the seed mass ratio changes from 0.25 to 0.5. In a similar......
., and the other chemical reagents were of analytical grade purchased from National Pharmaceutical Group, China. Sodium aluminate solutions were prepared by dissolving Al(OH)3 into heated NaOH solution... of sodium oxalate in sodium aluminate solutions were 0, 2, 4 and 6 g/L, respectively. The seed precipitation experiments were carried out in batch tanks, the temperature of which was controlled......
