The improvement of mass transfer in liquid-liquid extraction systems of pulsed packed columns has recently attracted much attention. The influence of nanoparticle and surfactant concentration on hydrodynamic characteristics and the mass transfer coefficient in the liquid phase were evaluated. The addition of nanoparticles increases the diffusion and mass transfer, but they are not stable in this system. One possibility to improve the sustainability of nanoparticles is the simultaneous application of a surfactant and nanoparticles. A slightly higher concentration of surfactant resulted in a significant improvement in extraction efficiency. The Newman, Krong, and Hendlos theories and chemical affinity model were applied to study the mass transfer in the chemical system with and without nanoparticles.

SiO2 纳米颗粒和表面活性剂对萃取效率的影响：灵敏度分析

脉冲填充柱液-液萃取系统中传质的改进最近引起了很多关注。评估了纳米颗粒和表面活性剂浓度对液相中流体动力学特性和传质系数的影响。纳米粒子的加入增加了扩散和传质，但它们在这个系统中不稳定。提高纳米颗粒可持续性的一种可能性是同时应用表面活性剂和纳米颗粒。稍高浓度的表面活性剂可显着提高萃取效率。应用 Newman、Krong 和 Hendlos 理论和化学亲和模型来研究有和没有纳米粒子的化学系统中的传质。
