A flow cell for the rapid and coulometric ion transfer at the aqueous| organic(W| O) interface(FECRIT) developed could be attained for the quantitative ion transfer with efficiency more than 99% within 1 min. When two-step FECRIT and a suitable ligand were adopted, the determination of Ca2+could be achieved with the efficiency of 99.9±0.1% based on the coulomb number for the transfer of Ca2+without any interference of coexistence cations. In the present work, new FECRIT for the coulometric determination of anions was also developed.
