Capacity of the resin
The adsorption capacity of the resin was calculated by the batch
technique. For this process, 100 mg resin, 200 mg L−1 Cd ions and PAR
solutions were stirred for 1 h with magnetic stirrer andfiltered through a
filter paper. Enriched cadmium ions onto polymer resin particles were
stripped with 5 mL HNO3–ethanol mixture and were determined by
FAAS [15,16]. As a result, capacity of the XAD-761 resin has been
obtained as 12.4 mg g−1
. Different resins with their sorption capacities
and enrichment factors were given in
