摘要: ABSTRACTA novel acrylic polyester hyper-dispersant was used to disperse titanium dioxide in different organic solvents. The adsorption behaviors were investigated ethyl acetate, toluene, and isopropyl alcohol. Meanwhile, the data of isotherms correlated using Langmuir, Freundlich, Redlich–Peterson, Tempkin, Fritz–Schlunder models. results showed that four-parameter isotherm equation best correlation. mean free energy sorption calculated by Dubinin–Radushkevick its E value 2.09–3.11 kJ mol−1, this indicated a physical process accordance with FTIR test result.
