Abstract

Abstract Shifts of the potentials of a calcium ion-selective electrode based on the complex of 7, 19-dibenzyl-2, 2, 3, 3-tetramethyl-7, 19-diaza-1, 4, 10, 13, 16-pentaoxacycloheneicosane- 6, 20-dione with calcium tetra (4-chlorophenyl) borate in various membrane solvents caused by changes in hydrodynamic conditions in the measured solution were examined. The use of 2-fluoro-2'-nitrodiphenyl ether as a membrane solvent combined with substitution of ...
