摘要: 由甲苯二异氰酸酯交联氧化β-环糊精与透析膜复合制得复合吸附剂,对尿素的吸附结果表明,复合吸附剂的透析膜既可有效地阻止人血清白蛋白与吸附剂接触,又可使尿素分子迅速透过膜而被吸附剂吸附,复合吸附剂能从人血清蛋白溶液中高选择性地吸附尿素,吸附量也有明显提高,由未复合时的10mg/g增至38mg/g.

Abstract: Anovel adsorbent with an aldo structure was obtained by the oxidation of acrosslinked p-cyclodextrin polymer. The highest urea adsorption capacity reached 56 mg/g at 37℃ and PH 7.4. The composite adsorbent was prepared by the oxidation of a TDIcrosslinked β-cyclodextrin resin and dialytic membrane. It was found that the compositeadsorbent has a higher urea adsorption selecitivity and capacity compared to that of theoxidation of a TDIcrosslinked p-cyclodextrin resin when urea is in aqueous human serumalbumin.

Key words: Oxidation of a TDI crosslinked β-Cyclodextrin, Dialytic membrane, Composite adsorbent
