雷尼替丁吡啶钌体系伏安行为的研究

Study on the voltammetric behaviours of ranitidine and Ru(bpy)_3^(2+) system

雷尼替丁是含呋喃环的胺类化合物,加入吡啶钌使其电化学行为发生改变,从而导致雷尼替丁和吡啶钌电化学发光共反应。本文采用循环伏安技术,详细地研究了该体系的电化学行为和电化学发光行为。实验表明在磷酸盐缓冲溶液中(pH7.50),雷尼替丁的电化学发光共反应体系,发光稳定性好、灵敏度高。

Ranitidine is a kind of amine containing a furan ring. When added Ru （bpy） 3^2＋ , the electrochemical behaviours of ranitidine will be changed, resulting in a electrochemiluminescence （ECL） co - reaction between ranitidine and Ru（bpy）3^2＋. In this paper, we studied in detail the behabiours of electrochemistry and electrochemiluminescence for the system. The experimental results show that the system consisting of ranitidine and Ru（ bpy）3^2＋ has advantages such as steady ECL signal and high sensitivity in phoshate buffer（ pHT. 50）.
