Abstract
A Y micromixer with a macroscopic mixing cavity at the inlet junction was developed. The effects of the mixing cavity on the improvement of extraction of copper by LIX 84I were investigated. The investigated parameters and their ranges were: overall flow rate: 10 – 200 mL/min; microchannel size: 0.5 – 1 mm and mixing cavity diameter: 5 – 20 mm. Extraction efficiency, volumetric mass transfer coefficient, kinetics and pressure drop were investigated. The extraction efficiency and the volumetric mass transfer coefficient in the cavity micromixer were significantly higher than the Y micromixer. The volumetric mass transfer coefficient ranged between 1 – 93 s -1 , and the pressure drop between 50 – 500 kPa. The residence time required in the micromixers was two orders of magnitude lesser than that of an agitated batch reactor.
期刊介绍：
Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
