Spectrophotometric Investigation of Cadmium Complex Solution with m-Bromobenzenediazoaminoazobenzene
摘要:
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 β-correction theory was applied instead of the single wavelength method. This study gave the simple determination of the complex ratio, real molar absorptivity(ε)and step or cumulative stability constant (K).
