Abstract
Para-Cresol-formaldehyde cationic resins partially substituted by sulp honated coconut shell charcoal were prepared. Physical measurements li ke absolute densities, swelling measurements, attritional breaking and exchange capacity studies were made. The ion exchange capacity of pur e sulphonated coconut shell charcoal is greater than that of pure resi n. For chemical systems requiring ion exchangers of small exchange cap acity, such inexpensive ion exchangers can be used.
