利用IR, 13C NMR和XPS等技术研究了仲胺型硝化纤维素(ACN)对肌酐(CRE)的吸附行为, 提出了可能的吸附路线. 光谱分析的结果表明在模拟人体生理条件下, ACN对CRE的吸附是通过碱化的硝酸酯基与CRE的胍基碳生成离子复合物达到的.

The adsorbing process of the cellulose nitrate containing secondary amino group (ACN) for creatinine was studied by IR, 13C NMR and XPS techniques. The results showed that under simulated biological conditions, the chemisorption of creatinine on the surface of ACN in dialysate could be attributed to the formation of ionic bond between the alkalized nitrate and the carbon atom of guanidine.
