Influence of sodium dodecyl sulphate micelles on the kinetics of complex formation between Pd(H2O)(4)(2+) and S-carboxymethyl-L-cysteine
Apstrakt
The kinetics of complex Formation between Pd(H(2)0)(4)(2+) and S-carboxymethyl-L-cysteine (SCMCH(2)) was investigated in the presence of sodium dodecyl sulphate in the acidity range between 2 M HClO4 and pH 5. Although the mechanism was not affected by the presence of anionic micelles, retardation (2.2 LT pH LT 5) and acceleration (pH LT 2.2) of the complex formation were observed compared with its rate in aqueous solution. These effects were interpreted in terms of the long-range electrostatic interactions between the negatively charged micellar surface and ligand species which can be in different ionic forms depending on the pH.
