ABSTRACT
In this sluuV the physicochemical properties of natural colloids sampled from deep granite groundwater were investigated to charaeleri/e the behaviors of natural colloids. I'he sampled natural colloids mainly consisted of organic materials and aluminosilicatcs which were distributed in the si/e range of about 1 - 10 nm. The concentration of natural colloids was about 6.264 nig I and about 95% of which were in the si/e range of I 10 nm. fhe data obtained from this stud)' will give useful information about the characteristics of natural colloid necessary for the exaluation of the roles of colloids in the migration of contaminants in the geological formations.
Keywords: natural colloids | characteristics of colloids | granite groundwater | ultrafiltration
