摘　　要：The interaction of O {2 [ α (2 hydroxy 5 sulphophenylazo)benzylidene]hydrazino}benzoic acid(ZCN) with cetyl trimethyl ammonium bromide(CTAB) was studied by UV spectra in pH=5 0 buffered solution. The results showed the complex has maximum absorption at 540 and 570 nm with an apparent molar absorptivity of 2 0×10 4 L/(mol·cm). Three constants were determined: binding constant K =2 3×10 5; degree of dissociation α =0 03 and binding number n (CTAB)∶ n (ZCN)=1∶2 5.The interaction of O {2 [ α (2 hydroxy 5 sulphophenylazo)benzylidene]hydrazino}benzoic acid(ZCN) with cetyl trimethyl ammonium bromide(CTAB) was studied by UV spectra in pH=5 0 buffered solution.
