Abstract
Amberlite XAD-8 resin adsorbs various kinds of organic compounds. The XAD-8 resin which adsorbed a cationic surfactant adsorbs acid dye but does not adsorb basic dye, while the XAD-8 resin which adsorbed an anionic surfactant adsorbs basic dye but does not adsorb acid dye. Therefore, it is possible to separate a dye from a mixed solution that contains acid dyes and basic dyes.
