ABSTRACT

Organized media have been extensively applied in various analytical methodolo­ gies to enhance their sensitivity and selectivity [1-6]. The success of such appli­ cations is due to the fact that organized systems can be employed to change the solubility and microenvironment of analytes and reagents and to control the reactivity, equilibrium, and pathway of chemical or photochemical processes among other effects [1, 2, 7]. These properties of organized media can also be

utilized to facilitate analytical chemiluminescence (CL) measurements [8-13]. Advantages cited include elimination of solubility problems [8, 9], improved sen­ sitivity [9-13], increased selectivity [9, 13] better precision [13], and a less strict pH requirement for observation of efficient chemiluminescence [9, 13].
