Zum extraktionsverhalten von liganden des CMAB-chinolin-8-ol-typs und die photometrische bestimmung von magnesium mit CMAS-chinolin-8-ol

Ultraviolet and light absorption spectrometry

“…A patent has been granted for the use of a similar class of crown compounds for determining various metals, including Li, Mg, and Ca, (322). A study of the extraction behavior of ligands analogous to 7-[«-(0-carbomethoxyanilino)benzyl]quinolin-8-ol has shown that their complexes with periodic group II (2 in 1985 notation) and III metals plus Bi, Co, Mn, and Pb are bidentate and not tridentate as previously suggested (400). Ternary complexes of periodic group III metals with eriochrome black T and diphenylguanidine and their extraction into butanol were studied and methods were developed for A1 in steel and A1 and Ir in the presence of other metals (29).…”
