摘要
研究了碱性条件下单态铝酸根离子与单态硅酸根离子的反应.实验结果表明,生成的硅铝酸盐沉淀与溶液中的Al、Si以及OH ̄-浓度有关.反应过程中存在过饱和现象.反应体系的OH ̄-浓度和反应物Si/Al比影响过饱和时间和过饱和区.
The reaction between mono-aluminate anions and mono-silicate anions in solution has been studied. Experimental results show that aluminosilicate precipitate is formed during the reaction.[Al],[Si] and[OH ̄-]in the solution affect the formation of the precipitate and when the reaction reach the equilibrium,[Si][Al]/[OH ̄-] ̄2=1.0×10 ̄(-3).The phenomenon of supersaturation exists during the reaction, which is affected by Si/Al and [OH ̄-] in reaction mixture.
