| 摘 要： | 研究了铬酸钠碳化反应动力学,在1个2 L反应釜内,通过监测反应过程中CO2压力的变化,计算反应速率,避免了因逆反应过快造成的溶液取样分析的困难。实验发现反应速率有一个下降-升高-下降的变化过程。通过反应机理分析,导出了动力学方程,并根据动力学方程较好地解释了实验现象。 |

| Abstract: | Carbonation kinetics of aqueous sodium chromate was studied. A 2 L autoclave was used as the reactor. Carbonation reaction rate was calculated by means of measuring the pressure change. A kinetics equation was proposed through analyzing the mechanism of the reaction. Based on the equation, the experimental results were explained well. |
| Keywords: | sodium chromate sodium dichromate carbonation kinetics |
