The quaternary ammonium cellulose nitrate(QACN) was prepared by reacting cellulose nitrate(with degree of subtitution 1.15) with 3-chloro-2-hydroxylpropyl-trimethylammonium chloride(CHPA). The substitution degree of nitrate in QACN was 1.03 and that of NR4 was 0.38. The structure of QACN has been confirmed by elemental analysis, IR, 13C NMR, and XPS. It has a good adsorption property for creatinine. The equilibrium adsorption ratio of QACN for creatinine was 49% at 37℃, at dosage of 0.5 g, pH=7 and creatinine concentration of 60 mg/L in 25 mL dialysate. The equilibrium time was 4 h.
