Oxidative chemiluminescence of some nitrogen nucleophiles in the presence of formic acid as an ancillary reductant

Flow-Injection Determination of Retinol and Tocopherol in Pharmaceuticals with Acidic Potassium Permanganate Chemiluminescence

“…The mechanism of enhancement by formaldehyde and related compounds has, as yet, not been fully elucidated. Various research groups have postulated that these species are oxidized to form excited-state carbon dioxide 24,25 or singlet oxygen; 26,27 some have even suggested that these enhancers increase the rate of analyte oxidation. 28 This study reports on a flow injection chemiluminescence (FI-CL) system for the determination of retinol and tocopherol, based on their enhancement effect on the KMnO4-HCHO CL reaction in an acidic medium.…”

Chemiluminescence from an Oxidation Reaction of Rhodamine B with Cerium(IV) in a Reversed Micellar Medium of Cetyltrimethylammonium Chloride in 1-Hexanol-Cyclohexane/Water

“…25 Although rhodamine B (RB) was often considered to be a sensitizer for the CL systems, 26,27 it was reported that CL emission could be generated by the oxidation of RB. Studies of the CL characteristics based on the oxidation of some xanthene dyes…”

Post-column detection of benzenediols and 1,2,4-benzenetriol based on acidic potassium permanganate chemiluminescence

“…The CL mechanisms of acidified potassium permanganate oxidation with some organic compounds are still not very clear so far. Some excited or active intermediates, such as triplet dimer of carbon dioxide [30], energy transfer to fluorophore [31,32], triplet state of a Mn(II) complex [33,34], or an autocatalytic effect [35], have been speculated, whereas most of the speculations had no convincing supporting evidences. Therefore, the details of the mechanisms remain to be investigated further.…”
