The adsorption of poly(ethylene glycol) (PEG) and ammonium poly(methacrylate) (APMA) onto alumina has been examined both individually and in combination. The adsorption density of APMA was found to be higher than that of PEG onto alumina. The adsorption isotherms of PEG and APMA for alumina exhibited a Langmuirian behavior. The adsorption density of PEG was significantly reduced in the presence of APMA, but the reverse was not true. About 60% desorption of PEG from alumina was achieved, while… CONTINUE READING
