Investigation of complex formation reactions of Fe(III) and Al(III) with some phenol derivatives by the method of ion exchange
Streszczenie
By the method of ion exchange on the exchanger Dowex 50
WX 8 100-200 mesh complex formation was investigated in the
system Me(ClO₄)₃ + XC₆H₄OH + HClO₄ + NaClO₄ + H₂O, with
Me = Fe(III) or Al(III) and X = Cl, Br, CH₃, NO₂. It was
proved that 1:1 complexes are formed between Me(III) and
a phenol molecule. Stability constants of the complexes
were determined and related with Hammett’s sigma constants.
