- 中文摘要:
The dissociation constants of m-, and p-phenylenediaminete-traacetic acid (m-, and p-, PDTA) have been determined potentiome-trlcally at room temperature (about 25℃) in an ionic strength of 0.10 M KNO3. The stability constants of their metal complexes have also been determined by UV spectroscopic, potentiometric, and polarographic methods. The formula of the metal complexes by spectroscopic and polarographic methods are both in good agreement to be 1:1. The order of the stability of the metal complexes is:
Cu>Ni>Zn>Co>Cd>Mg, Ca, Ba, Sr.
Which is in accordance with Irving-William stability order. - 英文摘要: --
