| 摘 要： | In this paper, the ion transfer process of bromocresol purple(BCP) across the liquid/liquid interface has been described. The effects of the supporting eletrolyte in two phases and solvent on the transfer behavior of bromocresol purple have been investigated in detail and the relationship between the ion transfer and concentration of electrolytes in the organic phase is explained in terms of the dissociation of TBA~+ anti TPB~- in the organic phase. The proposed transfer mechanism for BCP has been proved to be reasonable by UV-spectroscopy of the products of the electrolysis in aqueous phase. The standard potential differences △_0~wφ~0 and standard Gibbs energies △_0~WG~0 of BCP transfer from water to some organic solvents are calculated. The dissociation constants of BCP obtained are in agreement with the literature values.
