Electrochemical Studies on the Metal Complexes of Alizarin Fluorine Blue and Its 5‐Sulphonated Analogue

Abstract

used t o study the electrochemical nature o f the binary and ternary canlexes o f A l i z a r i n f l u o r i n e blue and i t 8 5-rulphonated analogue. The conditional constants o f certain metal complexes are evaluated and e f f o r t has been made t o determine the exact compositions o f these complexes. The +effect on the and i are discussed. d INTROWCTION Polarographic, c y c l i c voltamnetric and microcoulometric techniques have been The metal complexes o f A l i z a r i n f l u o r i n e blue ( M , N -d i (carboxymethyl )-mino Prosent Address : I n s t i t u t fur Strahlenchemie, I m Max-Plank I n s t i t u t fur Kohlenforrchung, S t i f t s t r a s s e 34-36, D-4330 nillhrim, a.d.Ruhr,W.Gennany.-9 -
