Abstract
The sodium ion transfer across the micro-water/1,2-dichloroethane interface facilitated by a novel ionophore, liquid crystal crown ether was studied s ystematically. The sodium ion transfer facilitated by LCCE is controlled by diffusion studied by cyclic voltammetry. The diffusion coefficient of LCCE in 1,2-dichloroethane was calculated to be equal to (2.61 +/- 0.12) X 10(- 6) cm(2)/s and the stability constant of the complex between Na+ and LCCE w as determined as lg beta (o) = 5.7 in 1,2-dichloroethane.
