摘要
研究了CaCO3、MgCO3在L-谷氨酸钠溶液中的浸出行为,根据同时平衡原理,分析了Ca(Ⅱ)-Mg(Ⅱ)-Glu^2--CO3^2--H2O体系中Ca(Ⅱ)和Mg(Ⅱ)的配合平衡热力学。计算结果表明,在7<pH<12条件下,溶液中的c(Ca^2+)T、c(Ma^2+)T随pH增大而降低,且会降到很低。
Leaching behaviors of CaCO3,MgCO3in L-monosodium glutamate solution were studied.The equilibrium thermodynamics of Ca(Ⅱ),Mg(Ⅱ)complexes in the Ca(Ⅱ)-Mg(Ⅱ)-Glu^2--CO3^2--H2O system were analyzed by the principle of simultaneous chemical equilibrium.The theoretical results are as follows:when pH is in the range of 7~12,the solubilities of CaCO3and MgCO3reduce with pH increasing,to very low level.
