The Study of Chemiluminescence of Acridinium Ester in Presence of Rhodamin B as a Fluorescer

The reaction of hydrogen peroxide and  pheny -۹-acridinecarboxylate in the presence of rhodamin B as a fluorophore leads to the emission of either bright blue light  or bright red light, depending on the structure of fluorescer and reaction conditions. The light emitter responsible for the Chemi Luminescence (CL) reaction is acridone and that the blue light produced with out the fluorescers is  a result of direct CL. The intensity and kinetic parameters for the CL systems were evaluated from fitting of the resulting intensity-time plots. The CL systems were investigated as concentration dependent of fluorescer, hydrogen peroxide, acridinium ester and sodium hydroxide as a catalyst.
