Abstract
Aggregation stability of low concentrations (10 mg/l) of aqueous dispersions of sulfate lignin is studied in a wide pH range (9.40–2.15) by filtration through track-etched membranes with pore sizes of 30–200 nm. It is shown that at all of the studied pH values, the solution of sulfate lignin is a polydisperse system. As pH decreases, the size of sulfate lignin particles increases, whereas the polydispersity of a system in the studied range of particles sizes (30–200 nm) decreases.
