Introduction Of Bentonite Purifi Ion Processing

are prepared using distilled water. Bentonite is submitted to a solid-state ion-exchange process by immersion into ZnSO 4.5H 2 O at 550–560 C for 10, 20, 40, 60 and 90 minutes. The process is conducted using 2 g of bentonite and 2 g of ZnSO 4. 5H 2 O. After the ion exchange process, the bentonite is washed
