SALT BRIDGES FOR MINIMIZATION OF LIQUID JUNCTION POTENTIALS IN DIFFERENT SOLVENT MEDIA

摘要

The main cause of high residual liquid junction potentials, and of consequent intrinsic errors, in direct potentiometric electroanalysis (plon and pH measurements) is the inadequacy of the salt bridge selected for insertion in the operational cell. Some recent acquisitions of salt bridges for aqueous and aqueous-organic solvent mixtures are presented.
