Studies of visible oscillating chemiluminescence in luminol-H2O2-KSCN-CuSO4 system using (2-hydroxyethyl) trimethylammonium hydroxide

摘要

Visible oscillating chemiluminescence (CL) of luminol-H2O2-KSCN-CuSO4 was studied using the organic base (2-hydroxyethyl)trimethylammonium hydroxide. The effect of concentrations of luminol, H2O2, KSCN, CuSO4 and the base were investigated in a batch reactor. This report shows how the concentration of components involved in the oscillating CL system influenced the oscillation period, light amplitude and total time of light emission. The oscillating CL with different bases was also investigated. Results indicated that using 2-HETMAOH causes regular oscillating CL with nearly the same oscillating period.
