الوصف: | Three water insoluble β-cyclodextrin polymers HP-β-CDP, CM-β-CDP and AE-β-CDP were synthesized by cross-linking epoxychloropropane with corresponding β-CD derivatives and utilized to adsorb water-soluble dye fuchsin from aqueous solution. FT-IR spectra confirmed the existence of hydroxypropyl, carboxyl group and amidogen in polymers. The influences of several parameters (contact time, pH and temperature) and the degree of substitution (DS) of CM-β-CDP in range of 1.5–4.5 on the adsorption capacity (Q e) were evaluated. The results showed that all maximum Q e of polymers appeared at pH 5.2–5.3. CM-β-CDP with carboxyl group was the most effective extractant, and the Q e of CM-β-CDP with DS 1.5–2.5 kept nearly constant but decreased sharply over 2.5. However, AE-β-CDP with amidogen had displayed a quite low Q e to fuchsin, even lower than that of unmodified β-CD polymer. The preliminary studies on the morphology of both CM-β-CDP and AE-β-CDP by AFM disclosed the differences in topography of their surfaces. |
