The thermosensitive polyelectrolytes were obtained by grafting 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) onto hydroxypropylcellulose (HPC); a biodegradable polysaccharide. The interactions of the polymers with dodecyltrimethylammonium chloride (DTAC); a model cationic surfactant; were studied. It was found by the measurements of the surface tension and the analysis of fluorescence emission of pyrene used as a fluorescent probe; that the HPC-AMPS graft polymers strongly interact with DTAC with the formation of polymer-surfactant complexes. The critical aggregation concentrations of these polymer-surfactant systems were found to be of the order of 10-5 mol/dm3. The polymers were found to be potentially useful in the purification of water from cationic surfactants. © 2006 Wiley Periodicals; Inc;
