| Abstract: | The adsorption and dispersion of calcium lignosulfonates (CLS) of different molecular mass on the surface of TiO 2 particle is studied in this paper There is a competitive sorption between water molecules and CLS on the solid surface Equilibrium isotherm for the sorption of CLS on TiO 2 surface accords with the Langmuir model On the surface of TiO 2,CLS molecules are adsorbed as spheres with the radius equal to or direct proportional to the radius of gyration The repulsion potential energy of CLS on the surface of particle is static repulsion potential energy and space steric potential energy, and static repulsion potential energy decreases and space steric potential energy increases with increasing molecular mass of CLS. |
