In this work, kraft lignin was modiﬁed via oxidation with nitric Dispersion acid under varied conditions to produce oxidized lignin (OL) with diﬀerent charge densities and molecular Charge density weights. The eﬀects of anionic charge density and molecular weight of the lignin based products on the dis- Colloid persion and sedimentation of kaolin particles were studied fundamentally. The adsorption of OLs on particles as Polymer adsorption well as the changes in the zeta potential, relative turbidity, hydrodynamic diameter and sedimentation of par- Molecular weight ticles under static (non-stirring) and dynamic (stirring) conditions were systematically investigated. Dispersion studies suggested that both charge density and molecular weight had great impacts on the stability of kaolin particles.
