In solvent extraction which is a useful method of separation of metals, we used N -lauroylsarcosine (NLS), containing tertiary amine which is alkyl amide derivative with the sarcosine moiety in the molecule structure in order to separate and recover these metal ions. We studied about the extraction equilibria of these metals using NLS. The selective extraction order of NLS is Ga(III) > In(III) >> Zn(II). It was found that NLS was able to separate these metals by pH difference. Versatic acid 10 (VA10) with only carboxylic acid group in the molecule structure extracted In(III) and Ga(III) simultaneously in the same pH region. Therefore, we found that the amide group included in the molecule structure of NLS has an important role to extract these metals. Mutual separation of In(III), Ga(III) and Zn(II) was carried out by a one-step experiment using NLS. Slope analysis was used to investigate the extraction equilibria of In(III) and Ga(III) with NLS. Suitable concentrations of acids were able to strip these metals from the loaded organic phase.","PeriodicalId":21805,"journal":{"name":"Solvent Extraction Research and Development, Japan","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67093712","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}

A cloud point extraction (CPE) method is proposed for the preconcentration of Eu(III) and subsequent determination was carried out by a fluorometric method using a microwell plate reader. Optimal experimental conditions were examined for fluorescence of the TTA chelate in the surfactant phase. Fluorescence was measured at λem = 616 nm after excitation at λex = 355 nm. The extracted species is estimated to be Eu(TTA)3(Triton X-114)1~2 and coordination is competitive between TTA and the oxygen atoms of Triton X-114 depending on each concentration. A content of Eu(III) was directly determined by a plate reader using 100 mm3 of surfactant phase without dilution. The fluorescence intensity, which was measured in a microwell, was a linear function of initial concentration from 1.0 × 10-8 to 8.0 × 10-6 mol dm-3 of Eu(III). The use of microwell plate system is convenient for handling small-volume samples.","PeriodicalId":21805,"journal":{"name":"Solvent Extraction Research and Development, Japan","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67093919","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}

In this study, we focused on reversed micellar extraction which is promising from the viewpoint of both costs and energy saving, and examined the extraction rate of methylene blue (MB) using sodium bis(2-ethylhexyl)sulfosuccinate (AOT) and di(2-ethylhexyl)phosphate (DEHPA). In the AOT/isooctane system, the overall mass transfer coefficient of the MB extraction, KW, decreased with increasing NaCl or KCl concentration. In contrast, in the AOT/2-ethyl-1-hexanol (EHA) and DEHPA/EHA systems, the effect of the KCl concentration was smaller. For the AOT/(isooctane + EHA) and DEHPA/(isooctane + EHA) systems, the KW value increased with increasing EHA concentration. However, the dissolution of MB in the organic solvent cannot be ignored at higher EHA concentrations. At the same concentrations of salt and EHA, the KW values of the AOT and DEHPA systems were almost the same. The dissociation state of DEHPA changed with pH, and the KW value decreased with decreasing pH. It was confirmed that the KW value for MB extraction was determined by the dissociated DEHPA concentration.","PeriodicalId":21805,"journal":{"name":"Solvent Extraction Research and Development, Japan","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67093594","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}

In this study, extraction of the toxic elements, arsenic, selenium, and antimony from acidic chloride media using the oxygen-containing compounds cyclopentyl methyl ether (CPME), dibutyl carbitol (DBC), and methyl isobutyl ketone (MIBK) was compared. Extraction of As(III) increases with increasing hydrochloric acid concentration and the extractability using CPME, DBC, and MIBK was similar. On the other hand, As(V) was not extracted at all using these extractants. Sb(V) and Se(VI) were extracted at high hydrochloric acid concentration. The order of extractability for Se(IV) in acidic chloride media was MIBK > DBC > CPME. The extraction of As(III) using CPME was examined under various conditions. As As(III) was extracted only at high hydrochloric acid concentration, arsenic trichloride (AsCl3) was suggested as the extracting species. CPME was not saturated with As(III) under the extraction conditions used in this study. As(III) can be enriched by the combination of extraction using CPME followed by back extraction using a small volume of distilled water.","PeriodicalId":21805,"journal":{"name":"Solvent Extraction Research and Development, Japan","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.15261/SERDJ.26.81","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67093730","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}
