摘要: 本文用电化学,吸收光谱等方法对Cu2+及其配合物与胆红素在碱性(pH10)条件下的作用规律进行了研究。发现Cu2+及其配合物对胆红素的氧化的催化作用依配合物的稳定性和配体齿数不同而异。在胆红素的氧化过程中,真正起氧化作用的是溶解氧。 |

Abstract: he reaction kinetics and reaction mechanism of cupric ion and its complexes with bilirubin in aqueous solution (pH10) have been investigated by using electrochemical technique,absorption spectrum, etc. It was found that cupric ion and its complexes can catalyze the oxidation of bilirubin. In the reaction process, it was considered, bilirubin combined with cupricion firstly, then it interacted with oxygen and was oxidized. The catalytic action of cupric complexes weakened with the increase of their stability. In this paper, the determination method for bilirubin, based on the oxidation reaction, has been discussed. |
Keywords: bilirubin oxidation of bilirubin cupricion and its complex catalytic reaction |
