N2 - The dissociation constant of 4-(8-quinolylazo)-1 aminonaphtalene (QAN) and conditional formation constants of its complexes with Cu(II), Ni(II) and Hg(II) were measured spectrophotometrically. The use of QAN as metallochromic indicator in copper, nickel and mercury titrations with EDTA was studied. QAN improves PAN and XO results in Cu(II) and Hg(II) titrations and is comparable to Murexide in Ni(II) titration. © 1984, Taylor & Francis Group, LLC. All rights reserved.
