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 4个常数均相对较小
The kinetic characteristics of aqueous dissolution of rock salt in Changshan of Zigong in Sichuan Province were studied systematically by conductivity method and self-made instruments. The results show that the quantitative relationship (ie, kinetic equation) between the conductance (L) or concentration (c) and the dissolution time (t) of the eluate during the dissolution process can be used at room temperature for different water injection fluxes Adsorption and adsorption or pressure or concentration of the relationship between the equation describes the formula, and the E constant and a constant with the flow (V) showed a linear increase, b constant and F constant but with the flow rate increases While decreasing linearly. Compared with static dissolution, the above four constants of dynamic dissolution are relatively small
