Isolation of lignosulfonate with low polydispersity index
摘要:
Lignosulfonate with low polydispersity index of 1.178-1.210 was isolated by gel column chromatography of Sephacryl S-100eluted with 0.2 mol/L of NaNO3 aqueous solution, whereas nearly monodisperse ligosulfonate fraction with polydispersity of 1.067can be obtained after chromatographic separation twice. This method provides an available approach to investigate the structure and characteristics of lignosulfonate.
