Recovery of rare metals and comprehensive extraction study using a novel acidic diamide-type ligand

Shimojo, Kojiro; Yabe, Makoto*; Sugita, Tsuyoshi; Okamura, Hiroyuki; Ohashi, Akira*; Naganawa, Hirochika

no journal, , 

Solvent extraction is an effective method for the separation and purification of metal ions. The extractant plays a key role in the extraction efficiency and the separation operation. In this study, we have synthesized a novel acidic diamide-type extractant and have comprehensively investigated the extraction of 56 metal ions. It was found that the novel extractant provides excellent extraction performance and separation ability for various rare metal ions such as Sc(III), In(III), Ga(III), and Ni(II) compared with conventional extractants.

Comprehensive extraction study of metal ions using an acidic diamide-type ligand

Solvent extraction is an effective method for the separation and purification of metal ions (e.g. recovery of rare metal and removal of toxic metal). The extractant plays a key role in the extraction efficiency and the separation operation. To date, much effort has been devoted to the development of novel extractants. Most approaches, however, have encountered problems on expensive production cost and low solubility in alkane solvents, and are far from ideal extraction system for practical use. In previous study, we developed inexpensively a diglycolamic acid-type extractant (DODGAA) with monoamide and carboxy group connected by an ether chain, and reported that DODGAA performed better than commercial extractants. In this study, we have synthesized a novel acidic diamide-type extractant (TONTADA) with diamide and carboxy group connected by a nitrogen donor, and have comprehensively investigated the extraction performance. It was found that the TONTADA selectively extracts valuable metal ions such as Cu(II), Ni(II), and Co(II) from base metal ions compared with DODGAA.

no journal, , 

Solvent extraction is an effective method for the separation and purification of metal ions. In previous study, we developed dioctyldiglycolamic acid extractant (DODGAA) with an amide group and a carboxy group connected by an ether chain, and reported DODGAA performs better than commercial extractants. In this study, we have synthesized a novel acidic diamide-type extractant (TONTADA) with two amide groups and a carboxy group connected by a nitrogen donor atom and have comprehensively investigated the extraction of 56 metal ions. It was found that the novel extractant TONTADA provides excellent extraction performance and separation ability for various rare metal ions such as Sc(III), Cu(II), Ni(II), Co(II), In(III), Ga(III), Hg(II), platinum-group metal, Hf(IV), V(V), Mo, W(VI), and Re(VII) compared with conventional extractants and DODGAA.

Calix[4]arene diglycolamic acid derivative; Application to lanthanide extraction

Shimojo, Kojiro; Yabe, Makoto*; Sugita, Tsuyoshi; Okamura, Hiroyuki; Ohashi, Akira*; Naganawa, Hirochika

no journal, , 

Solvent extraction is an effective method for the separation and purification of metal ions. The extractant plays a key role in the extraction efficiency and the separation operation. In this study, we have synthesized calix[4]arene diglycolamic acid derivative as a novel extractant and have investigated extraction behavior of lanthanide ions. It was found that the pre-organization of four diglycolamic acid groups in the cyclic structure can improve remarkably extraction performance and separation ability for lanthanide ions.
