Effect of Catlyst on Luminol -Hydrogen Peroxide–Water Chemiluminescence System

The Chemiluminescence properties of Luminol – Hydrogen peroxide reaction was studied in aqueous medium with different catalysts (CuSO₄.5H₂O, K₃Fe(CN)₆ and CrCl₃). It was observed that CL-behavior like I_max and τ1 depend on the catalyst in aqueous medium. Among the catalysts used, CuSO₄.5H₂O is the best catalyst. The study is useful for the determination of analyte by CL method.
