Abstract: The TY4 clay which has a lot of positive charge with weak acidity somewhere in Southwest China was chosen. A dynamic experiment was deliberately designed to establish the curve of uranium’s density related to flux and pH after appending 5%Ca(OH)2 as adsorption material to make simulating poles. The experimental results showed that the capability of adsorption was reinforced with increasing height and the average penetration coefficient was reduced . The pole’s adsorption capability was reinforced when the pH was near 11 and 9.
Key words: clay； dynamic simulation experiment；additive；U adsorption；pH
