    • Abstract


      The complexation reactions of La(III), Ce(III), Pr(III), Nd(III) and Sm(III) ions with pyrogallol have been studied by potentiometric method at various ionic strengths and temperatures. In acidic solutions, the formation of monopyrogallolate derivative of these metal ions has been indicated even in the presence of large excess of pyrogallol. The thermodynamic stability contants and thermodynamic parameters are also reported.
