%X The relative molecular mass and relative molecular mass distribution of electro-oxidative degradation products of sodium lignosulfonate were determined using a Waters ALC/GPC 244 apparatus comprising a mu-Ultrahydrogel 250 column and a differential refractometer index detector. The influences of the mobile phases on the elution behaviors of the samples are discussed. It is confirmed through a series of experiments that the eluent of a neutral aqueous solution containing low concentration of electrolyte could separate the components of the degradation products of lignosulfonate. The best results were obtained by using 0.05 mol/L LiCl solution with pH 6.5 as the eluent.
