摘要: The protonation and complex formation equilibria of N,N′-ethylenediaminedisuccinic acid (EDDS) in the isomeric form [S,S] a mixture EDDS isomers (25% [S,S], 50% [R,S], 25% [R,R]) with Fe(III), Cu(II), Zn(II) Mn(II) have been studied aqueous 0.1 M NaCl solution at 25 °C by potentiometric titrations. calculations were carried out computer program SUPERQUAD.
