对碘苯酚在金纳米微粒催化的化学发光体系的增强作用研究及其应用

发布时间:2021-12-01 22:09
  化学发光(Chemiluminescence,CL)是化学反应过程中的一种光辐射现象。溶液相中的化学发光反应大多是基于氧化还原反应。在化学反应过程中,产物从反应中获得能量,从基态跃迁到激发态,分子从激发态回到基态的过程中以光子的形式释放能量,即化学发光。化学发光分析法是一种分子发光光谱分析方法,主要是基于待测化合物的浓度与在一定条件下的CL强度之间的线性关系进行定量分析。常见的化学发光分析体系有过氧草酸酯化学发光(Peroxyoxalate Chemiluminescence,PO-CL)体系、光泽精(Lucigenin)化学发光体系、联吡啶钌电致化学发光体系、鲁米诺(Luminol)化学发光体系等。其中,鲁米诺化学发光体系是最常用的一种化学发光体系,已被广泛应用于药物分析、环境分析和生物分析等领域测定不同的目标分析物,包括金属离子、葡萄糖、维生素、蛋白质、核酸、环境污染物等。然而,在碱性条件下,鲁米诺的自身化学发光反应强度非常弱。因此,发展有效的催化剂和增强剂对新型发光体系的发展及应用具有重要意义。鲁米诺体系常见的催化剂包括金属离子、天然酶、纳米材料等。而增强剂则主要用于过氧化物酶(...
