ARTICLE J. Cent. South Univ. (2019) 26: 304-311 DOI: https://doi.org/10.1007/s11771-019-4002-1 Equilibrium concentration of lithium ion in sodium aluminate solution HUANG Wen-qiang(黄文强), LIU Gui... variation of lithium ion in sodium aluminate solution with addition of synthetic lithium aluminate was investigated. Elevating temperature, increasing caustic soda concentration, reducing alumina......
characteristics, this new peak at about 370 nm is determined as the evidence of a new species of aluminate ion with a coordination number of 6. Key words: sodium aluminate solution; UV spectrum; IR absorption; Raman spectrum; aluminate ion  ......

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......
- with the band at about 550 cm-1 and polynuclear aluminate ion with the bands at about 880 cm-1 and 635 cm-1, indicates that the dynamic balance among some aluminate species present in sodium aluminate...-alanine. Because Al (OH)4- is a main aluminate ion in sodium aluminate solution under the experimental conditions[12], the possible interaction between α-alanine and Al (OH)4- could occur due......
molecule in the transformation of low coordinated aluminate ion into high coordinated aluminate ion[14]. It can be deduced from Fig.2 that, compared with the blank, Na+ promoting gibbsite crystallization... effect of glutamic acid on sodium aluminate solution results from the hydrogen bond action between aluminate ion and glutamic acid. The schematic diagram of the hydrogen bond action between aluminate ion......
mechanism of oxalate The gibbsite precipitation from sodium aluminate solution during the seed precipitation process is listed in Eq. (7). It shows that Al(OH)4- is the main ion for the decomposition... J. Cent. South Univ.
