ISOTACHOPHORETIC SEPARATION OF POLYOLS IN BORIC-ACID SOLUTIONS

This work deals with a new approach to fractionation of polyhydroxyl compounds and amphoteric ions. The new technique is based on isotachophoresis of borated polyols leading to pH gradient formation. The Theoretical section contains a number of equations to determine pH values for different borated polyol ion zones on the basis of their absolute electrophoretic mobilities or concentrations. The Experimental section gives a description of tentative experiments demonstrating the possibility of isotachopoietic separation of polyhydroxyl compounds.
