摘要： 研究了SDS胶束介质中萘敏化双乙酰的室温磷光,认为SDS增强了萘与双乙酰的能量转移效率,敏化磷光强度与Poisson分布有关,并由胶团中含较少给(受)体的PDless×PAless决定。选择了最佳实验条件,该法简便、快速,萘的检出限达6.5×10-8mol/L.

Abstract: Micelle organizes the donor and acceptor molecules into a discrete volume region, facilitates the energy transfer and enhances the intensity of sensitized RTP.This paper reports the sensitized RTPof biacetyl by naphthalene in SDSmicellar solution, and indicates that the intensity of sensitized RTPwas correlative with the Poisson distribution and determined by values of PDless×PAless which is the probability of less donor and less acceptor occurred in the same micelle.The linear range of detection is 0-8.0×10-5mol/L.Typically, the limit of detection for naphthalene in SDSis 6.5×10-8mol/L.
