文摘The synthesis of a new ligand, m-bromobenzenediazoaminoazobenzene (m-BBDA) was carried out. The reaction between m-BBDA and cadmium(II) was sensitive at pH over 12 and in the presence of emulsifier OP. Because of the high interference of excess of ligand beta-correction theory was applied instead of the single wavelength method. This study gave the simple determination of the complex ratio, real molar absorptivity (epsilon) and step or cumulative stability constant (K).
