摘要
采用电导法和自制的仪器对四川自贡长山岩盐在动态条件下水溶溶解的动力学特征进行了系统的研究。结果表明 ,在室温下 ,对于不同的注水流量 ,溶解过程中溶出液的电导 (L)或浓度 (c)与溶解时间 (t)之间的定量关系 (即动力学方程 )均可用与Langmuir等温吸附时吸附量和压力或浓度间的关系方程相似的公式描述 ,且其中的E常数及a常数均随流量 (V)的增加而呈现线性增大 ,b常数和F常数却随流量的增大而线性减小。与静态溶解相比较 ,动态溶解时的上述
Kinetics characteristics of resolving of rock salt of Changshan in dynamic state have been studied by using conductance method and equipment made by ourself. The results show that the quantitative relationship between conductance(L) or concentration (c) of resolving solution in the process of resolving of rock salt and time t ( kinetics equation )is analogous to Langmuir equation for different flows in ambient temperature.Constant E or a increases with the increase of the flow( V ), whereas constant F or b constant decreases. The above 4 constants in dynamic state are smaller than those in static state.
