Abstract
The interaction of Al(III) with the anions of benzylpenicillin (Bzp–) and carbenicillin (Carb2–)in an aqueous solution at 25 °С and the ionic strength of 0.1 (KNO3)solution was studied by means of the pH-metric titration. The formation of complexes AlBzp2+ (lg β = 3.6±0.1) and AlCarb+ (lg β = 4.10±0.08) in the slightly acidic medium was established.
