Abstract

The dispersion behaviors of nano-ATO in aqueous system were studied in this paper firstly.Influences of the value of pH,type and content of dispersants,different dispersant time and processing parameters on the dispersion stability were discussed.The results indicated that the isoelectric point was in the place that pH=2,the dispersion stability was enhanced remarkably in neutral system.The optimum dispersant was A-187,the content in dispersion system 13%,and dispersed by 30 minutes.The slurry was stable by the optimum dispersant and the dispersing process.
