Abstract: The adsorption of some textile dyes such as Indigosol Blau IBC, Iyozol Turkish G, Iyozol Black B, Remazol Brilliant Orange 3R, Remazol Brilliant Violet 5R, Remazol Blau 3R, Sumufix Red 3BF and Everzol Yellow 4GL with crosslinked poly(N-vinylpyrrolidone) was investigated. Adsorption of these textile dyes onto crosslinked poly(N-vinylpyrrolidone) was studied by batch adsorption techniques at 25degreesC. The adsorption isotherms obtained were L-type (Langmuir-type) according to the Giles classification system. Adsorption studies indicated that monolayer coverage of the crosslinked poly(N-vinylpyrrolidone) by the dyes studied increased in the order: Indigosol Blau IBC > Iyozol Turkish G > Sumufix Red 3BF > Iyozol Black B > Remazol Brilliant Orange 3R > Remazol Blau 3R > Everzol Yellow 4GL > Remazol Brilliant Violet 5R. Values of the removal efficiency of the dyes ranged from 21% to 81%.
