The extraction of various metals by N,N,N',N'-tetraoctyldiglycolamide (TODGA) from nitric acid to ndodecane was investigated. It was obvious that divalent Ca (ionic radius: 100 pm), trivalent and tetravalent ions with ionic radii of 87–113 and 83–94 pm are highly extractable by TODGA. The limits of metal concentration (LOC) for Ca(II), Nd(III) and Zr(IV) in the extraction solvents, TODGA/n-dodecanen, TODGADHOA(N,N-dihexyloctamide)/n-dodecanen, TDDGA (N,N,N',N'-tetradecyldiglycolamide) and TDdDGA(N,N,N',N'-tetradodecyldiglycolamide) were determined. It is evident that LOC is influenced strongly by and increases with DHOA concentration and the length of alkyl chain attached to N atom of DGA.
