## Abstract Samples of a cationic sulphonated resin have been prepared by sulphonation of a mixture of phenol with cellulose acetate in the presence of paraformaldehyde as a crosslinking agent. The samples having average swelling percentage of 123, and a cation exchange capacity of 2.6 meq g^−1^ re
## Abstract In the present work, thiourea‐formaldehyde (TUF) chelating resin was synthesized and used in the adsorptions of selenite (SeO) and selenate (SeO) ions. The effects of initial acidity and initial selenium concentrations on the adsorptions were examined by batch technique. The synthesized
