Abstract
SINCE the description of the electrophoresis of amino-acids by Wieland and Fischer1 several workers2,3 have made observations on the ionophoresis of inorganic ions inside filter paper. However, these studies were purely theoretical and did not indicate the possibility of separating inorganic ions for analytical purposes. Preliminary work in this laboratory4 has shown that with the use of 1 N hydrochloric acid as electrolyte and 70 volts, a number of mixtures of metal ions can be separated into three fractions : anionic, cationic and isoelectric.
