摘要
通过Al Ferron络合比色动力学分析 ,对Al(Ⅲ )的形态进行了较为准确的划分和计算 ,考察了工艺条件对动力学参数和铝形态分布的影响 .研究表明 ,铝的初始浓度、合成温度对Alb 与Ferron的解离 络合反应的速率常数kb 有一定的影响 ,而碱化度、合成时的搅拌强度和加碱速度对kb 的影响不大 ;碱化度、铝的初始浓度对铝的形态分布影响很大 ,搅拌强度、合成温度和加碱速度对铝的形态分布也有一定的影响 .
The species distribution of aluminum and kinetics parameters have been investigated by analysis on the kinetics process of Al Ferron complex colorimetric and by true calculation of the three species.The results show that initial Al concentration and temperature affect the rate constant( k b)of Al and Ferron while basicity,mixing intensity and base injection rate affect a little.Basicity,initial Al concentration affect the species distribution evidently,mixing intensity,temperature and base injection rate also have effect on it.
