| Abstract: | OBJECTIVE:To study the electrochemical characteristic of acetyispiramycin transfer across the liquid/liquid interface.METHOD:The cyclic voltammogram was observed and Parameters related to interfacial behaviour were calculated by cyclic voltammetry.RESULTS:Acetylspiramycin transfers from water to nitrobenzene over the range of pH 2-9. The standard transfer potential and Gibbs energy were calculated as 162mv and -1.5KJ/mol.CONCLUSION:The transfer process of acetyispiramycin is a reversible one that is controlled by the diffusion. Results of study will be helpful to understand deeply the pharmacology and effectiveness of acetylspiramycin. |
