A urea adsorbent with an aldo structure was obtained by the oxidation of a crosslinked β‐cyclodextrin polymer. The highest urea adsorption capacity reached 50.6 mg/g in 0.05 M aqueous phosphate buffer at 37°C and pH = 7.4, and decreased to 4.0 mg/g in aqueous human serum albumin. The novel composite adsorbent was prepared by the oxidation of a crosslinked β‐cyclodextrin and cellulose dialytic membrane. It was found that the composite adsorbent had a higher urea adsorption selectivity and capacity compared with that of the oxidation of a crosslinked β‐cyclodextrin adsorbent when urea is in aqueous human serum albumin.
