铝酸钠溶液净化的物理化学研究

Physical Chemistry Of Sodium Aluminate Solution

本文研究了向不同成分的工业铝酸钠溶液添加BaO,以脱除SOi_4^(2-)、SiO_3^(2-)和苛化Na_2CO_3的反应,并对生成物进行了物相分析,探讨了反应的过程和条件,种分母液的净化综合效果良好。还对各净化反应的物理化学进行了研究。

This paper studies the reaction of removing SiO_4^(2-), SiO_3^(2-) and Na_2Co_3 out of industrial sodium aluminate solution with different compositions by adding the additive BaO. The phase-content of product is detented and the conditions and processes are discussed. It shows that the comprehensive effect of purification on the solution gained throught dissolving seeds is good. The physical chemistry of different purification reaction is also studied.
