Abstract

Abstract: The fluorescence quenching behaviour of naphthols by copper ion has been studied in different concentration of anionic sodium lauryl sulphate micelle. Various quenching processes have been analyzed to explain the quenching efficiency. The quenching behaviour of naphthols and naphtholates explained by a biphasic model consisting of two phases i.e.(a) quenching spheres containing the excited fluorophores and the quenchers resulting in transient component (for ROH*) and (b) the bulk phase where quenching is dynamic or diffusional (for RO¯*). The probable number of quenchers present in the quenching sphere of action has been calculated. [ABSTRACT FROM AUTHOR]
