As analog compounds of DGA (diglycolamide), MIDOA(methylimino-diacetamide) and TDGA(thia-diglycolammide) are used for the extractants of platinum group metals. These extractants can be extracted noble metals and oxyanions, which followed by HSAB theory. The high concentration of these metals can be also extracted by these compounds. The research of metal-complex structures gives the information on the ability and role for complex-formation, which will be useful for the development of novel extractants.

The metal-anions formed in acidic solutions can be extracted using extractants having amino N donor, which is protonated and formed to cationic extarctant there. However, there is few systematic results using this ion-pair extraction, and the extraction behavior needs more information. Therefore, we conduct experiments using different aqueous and organic phases. The disuribution ratios of Pd, Zr, Hf, Nb, Ta are over 100, and Ru, Rh, Nb, and Ta, those are considered to be hard to extract, can be extracted using this method.
