| Abstract: | Objective:To characterize the sodium polystyrene sulfonate. Methods: The physiochemical behaviors of sodium polystyrene sulfonate with different particle sizes, such as water retention capacity, exchange capacity, swelling coefficient and wet true density, were measured. Results:The particle size of sodium polystyrene sulfonate was inversely proportional to water retention capacity, exchange capacity and swelling coefficient. However, wet true density decreased proportionately as the particle size reduced.Conclusion: The physiochemical properties of sodium polystyrene sulfonate were closely associated with the particle size. |
