Abstract

âº Humic substances (HS) are characterized in terms of RH, size, and charge in CZE. âº HS are of nanometric dimension whatever the ionic strength and alkaline counter-ion. âº Electrophoretic mobilities are related to electrolyte composition. âº Weak HS-alkali metal interactions affect HS electrophoretic transport.
