Abstract
The interaction of Al(III) with ampicillin (Amp–) and amoxicillin (Axn–) in an aqueous solution at 25 °С and the ionic strength of 0.1 (KNO3) was studied by means of pH-metric titration. The formation of complexes AlAmp2+ (log β = 5.11±0.06), AlHAmp3+ (log β = 9.63±0.07), AlAxn2+ (log β = 4.64±0.09), AlHAxn3+(log β = 7.95±0.09) was detected.
