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.","PeriodicalId":21805,"journal":{"name":"Solvent Extraction Research and Development, Japan","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67093808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its separation performance of Am-241 with Eu-152 in nitric acid solution was investigated. The extraction kinetics were fast and could reach equilibrium within 15 min. When [HNO 3 ] = 0.1 M, the maximum SF Eu-152/ Am-241 was obtained as 124. Moreover, with increase in the concentration of HNO 3 , the extraction ability decreased gradually, and SF Eu-152/ Am-241 decreased as 3 when [HNO 3 ] reached 4 M. Back extraction was successfully completed by using 1 M guanidine carbonate with 0.5 M ethylenediaminetetraacetic acid (EDTA) or 1 M guanidine carbonate with 0.5 M diethylenetriaminepentaacetic acid (DTPA), respectively.

The extraction order of heavy rare earths in n -octane: n -octanol = 9:1 diluent was as follows: DIPDODGA > DPDODGA > TODGA > T2EHDGA. Alkyl chain shows great influence on extraction ability and the extractants with short chain can effectively extract heavy rare earth ions even at a concentration of less than 1.0 mol/L. The extraction mechanism was proposed with the results of slope methods, IR (Infrared) spectrometer and DFT (Density Functional Theory) theoretical study.
