Abstract
Cation exchangers have been prepared from cork charcoal obtained at te mperatures of 300, 400, 500, and 600-degrees-C by sulphonating with su lphuric acid and 10 and 20% oleum at 80, 100, and 120-degrees-C. Some of the exchangers obtained had an exchange capacity around 2 meq g-1 a nd very high thermal stability.
