    Description / Table of Contents: Zusammenfassung Die Bildung der Komplexe vonPAN in den SystemenLn(III)—PAN—Alkohol-Wasser (Ln(III)=Ho, Lu; Alkohol=Ethanol,n-Propanol,iso-Propanol) wurde mit einer spektrophotometrischen Methode untersucht. Die Gleichgewichtskonstanten der ReaktionenLn 3+ + HL⇌LnL 2+ + H+ (HL==PAN) und die Stabilitätskonstanten der KomplexeLnL 2+ wurden berechnet.
    Notes: Abstract The formation ofPAN complexes in the systemsLn(III)—PAN—alcohol-water (where:Ln(III)=Ho, Lu and alcohol=ethanol,n-propanol,iso-propanol) was investigated by a spectrophotometric method. Equilibrium constants for the reactionLn 3+ + HL⇌LnL 2+ + H+ (HL=PAN) and stability constants of complexesLnL 2+ were calculated.
