“…Also the other reason, for which transport rate for Ag + is better than other present metal cations, is its ionic size (0.126 nm). It is comfortable [11][12] with cavity size of the ligand (0.26-0.32 nm). So, Co(II), Ni(II), Zn(II), Cu(II), Cd(II) and Mn(II) cations were considered as interfering ions in the competitive transport experiments.…”
