Je. Atwater et al., REAGENTLESS FLOW-ANALYSIS DETERMINATION OF HYDROGEN-PEROXIDE BY ELECTROCATALYZED LUMINOL CHEMILUMINESCENCE, Analytical letters, 30(1), 1997, pp. 21-31
Flow analysis methodology is presented for the determination of microm
olar levels of aqueous hydrogen peroxide by luminol chemiluminescence.
Adjustment of the pH to alkaline conditions and addition of the lumin
ophore are implemented using in-line flow-through beds containing crys
talline media. The requirement for a homogeneous catalyst is eliminate
d by electrochemical initiation of luminescence. Traditional laborator
y reagents are replaced by packed beds containing solid phase basifica
tion media, and crystalline luminol. The methodology is suitable for a
pplication in both continuous flow and flow injection analysis configu
rations.
