Abstract
The polymeric matrix of m-cresol-formaldehyde sulphonated cationic res in was partially substituted by different amount of sulphonated charco al obtained from Emblica officinalis bark. These matrices are characte rised by physical measurements like absolute density, attrition percen tage and swelling. The exchange capacity of each of the matrices is fo und out fdr the exchange of Na+, Ca++, Mg++ and Zn++ ions respectively . It has been found out that the substitution of charcoal up to 20 per cent in the phenolic resin is economical.
