Tsung-Yuan Huang et al.
Luminescence : the journal of biological and chemical luminescence, 26(2), 118-124 (2010-02-16)
A novel phenomenon of dual chemiluminescence (CL) was observed for the KIO4-luminol-Mn(2+) system in strong alkaline solutions using the stopped-flow technique. Scavenging study of the reactive oxygen species (ROS) suggested that the two CL peaks originated from different CL pathways
Hong Xu et al.
Luminescence : the journal of biological and chemical luminescence, 21(3), 195-201 (2006-04-29)
The effects of 36 organic compounds on luminol-KIO(4)-H(2)O(2) chemiluminescence (CL) were studied. It was found that most of the tested compounds could inhibit or enhance the CL intensity. The activities of such inhibitors or enhancers were related to the pH
Yu-Cheng Chen et al.
Luminescence : the journal of biological and chemical luminescence, 25(1), 43-49 (2009-07-25)
Chemiluminescence (CL) from the oxidation of luminol with potassium periodate in strong alkaline solutions was greatly enhanced by the combined effect of gallic acid, acetaldehyde and Mn(2+). The CL spectra exhibited only one emission band at 425 nm, indicating 3-aminophthalate

Annali di chimica, 94(11), 829-836 (2005-01-01)
The catalytic effect of manganese (II) on the oxidation of the azo dye 3-Methyl-6-(2-hydroxyethoxy)-2-[2-methoxy-4-N (N, N diethylamino) phenylazo] benzothiazolium methylsulphate, with potassium periodate in the presence of 1,10-phenanthroline in weakly acidic media was studied. The reaction was followed spectrophotometrically by
Jianxiu Du et al.
Luminescence : the journal of biological and chemical luminescence, 25(1), 76-80 (2009-07-25)
A simple and sensitive chemiluminescence (CL) method combined with flow injection technique was developed for the determination of naproxen. It was based upon the weak CL signal arising from the reaction of KIO(4) with H(2)O(2) being significantly increased by naproxen
