Abstract


The dissociation constants of  o-(N-2-pyrolidimino) ethane sulphonic acid (H2PE), stability constant and thermodynamic parameters of its chelates with VO^2+, UO^2+ 2,  Cu(Il), NL(II), CO(II), Zn(II) and Cd(II) have  determined potentiometreicallv in aqueous medium (u = 0.01 M, 0.05 M and 0.1 M NaCIO4  by  Bejurrun’s method at 25, 35 and 45°C. The solid cornplcxes and their pyrdine and  picoline adducts have been synthesized and physiochemically studied.


Keywords


o-(N-2-pyrrolidimino)ethane sulphonic acid chelates; stability constants; dissociation constants.
