摘要

探索了微通道乳状液膜萃取Zn²⁺的主要影响因素及参数范围;然后对萃取过程中总流量Q、微通道片数P、微通道高度H等影响因素进行3因素3水平的正交实验及响应曲面分析,得出微通道液膜萃取Zn²⁺的最佳工艺条件。结果表明,3D-SPM在0.48 s的萃取时间内即可接近萃取平衡,实现对Zn²⁺的连续高效乳状液膜萃取,该方法为工业液膜萃取过程提供了新的技术路线。

Abstract

Main influencing factors and parameter range for Zn²⁺ extraction by microchannel emulsion liquid membrane are explored.The orthogonal experiment method is used to carry out three-factor three-level orthogonal experiment and response surface analysis on the influencing factors such as total flow Q,the number of microchannel P,and the height of microchannel H during the extraction process.The optimal technological conditions for Zn²⁺ extraction by microchannel liquid membrane are obtained.It is shown that 3D-SPM can approach the extraction equilibrium within 0.48 s,and realize the continuous and efficient extraction to Zn²⁺ by emulsion liquid membrane.This method provides a new technical route for industrial liquid membrane extraction process.
