• This paper presents detailed numerical evaluation of the Hermans-Fujita's general equation for the electrophoretic mobility of a coiled polvelectrolyte molecule in salt solution. Values of the electrophoretic mobility u_p are obtained as functions of values of two basic parameters σ and β; here σ is Debye's "shielding ratio," and β is the radius of the polymer coil relative to the thickness of the diffuse double laver. It is shown that the criticism offered recently by Overbeek and Stigter for the validity of Hermans-Fujita's u_p equation is doubtlessly incorrect. A procedure is demonstrated by means of vvhich u_p vs. β curves for different fixed values of σ can be reduced approximately to a single curve. The approximate solution for the same problem obtained by Overbeek and Stigter is discussed and compared with the rigorous treatment in relation to this reduction procedure.
