Özet

Adsorption of poly(2-hydroxypropyl methacrylate) on alumina from dimethylformamide was studied by ultraviolet (UV) and Fourier transform infrared (FT-IR) photoacoustic spectroscopy (FTIR PA) techniques. Adsorbent amount and concentration effects were investigated. The adsorption results are in conformity with Langmuir's isotherm. The differences observed in Langmuir parameters were explained by polymer-polymer, polymer-solvent, polymer-adsorbent, and solvent-adsorbent interactions. The fraction of carbonyl groups attached to the surface of alumina was calculated with a curve-fitting computer program. (C) 2002 Wiley Periodicals, Inc.
