Ultrasensitive Chemiluminescence Detection of Indoleacetic Acid Catalyzed by Silver Nanoparticles
Abstract:
A flow injection chemiluminescence (CL) method has been developed for the determination of indoleacetic acid (IAA). It is based on the fact that the weak CL of Ce(IV)-Ru(phen)32+ system is strongly enhanced in the presence of silver nanoparticles. Optimum conditions and possible mechanisms have been investigated. Under optimum experimental conditions, the linear range is from 1.0×10-8 – 6.0×10-7 g mL-1 with a detection limit 9.0×10-9 g mL-1
