摘要：
The adsorption of sodium dodecylbenzenesulfate (SDBS) on nanosized CaCO3 was studied. The change of zeta potential of dispersive system was discussed after SDBS was adsorbed. Moreover, the influence of SDBS amount and pH on the dispersion of nanosized CaCO3 in water was analyzed respectively. The results showed that the adsorption of SDBS on nanosized CaCO3 was spontaneous and reached saturation when the concentration of SDBS exceeded 2g/L. After SDBS was adsorbed on nanosized CaCO3, the change of zeta potential was great. Both SDBS amount and pH had an impact on the dispersion of nanosized CaCO3 in water.
