A possible scheme of electrochemiluminescence generation on platinum cathodes in aqueous solutions of peroxydisulfates

Electroanalysis of ascorbic acid (vitamin C) using nano-ZnO/poly(luminol) hybrid film modified electrode

“…Furthermore, luminol has been extensively used in chemiluminescence detection [39][40][41] and electrochemiluminescence [42][43][44][45]. An amino group in luminol serves as electron-donating group due to its positive mesomeric effect and enhances the chemiluminescence intensity resulting from reactions on the hydrazide group.…”

Cathodic electrochemiluminescence of the peroxydisulphate–ciprofloxacin system and its analytical applications

“…The SO 4 •− formed can chemically oxidize electrogenerated HO 2 • to give molecular oxygen in both triplet and singlet states (equations 4 and 5) . The regenerated triplet molecular oxygen ( 3 O 2 ) was electrochemically reduced again (equation ), resulting in the increase of the cathodic peak current of dissolved oxygen at −1.01 V. The formed singlet molecular oxygen ( 1 O 2 ) further partly combined through collision to become energy‐rich precursor singlet molecular oxygen pairs [( 1 O 2 ) 2 ] .…”

“…• to give molecular oxygen in both triplet and singlet states (equations 4 and 5) (22,23). The regenerated triplet molecular oxygen ( 3 O 2 ) was electrochemically reduced again (equation 1), resulting in the increase of the cathodic peak current of dissolved oxygen at −1.01 V. The formed singlet molecular oxygen ( (2) When 2.0 × 10 -4 mol L -1 CPF alone was present in 0.1 mol L -1 phosphate buffer solution (pH 6.1) without deoxygenization, a reduction peak appeared at −1.64 V [ Fig.…”

Nanocomposite of electrochemically reduced graphene oxide and gold nanoparticles enhanced electrochemilunescence of peroxydisulfate and its immunosensing abililty towards human IgG

“…The ðSO ÅÀ 4 Þ can undergo an electron-transfer reaction with an ECL luminophore to emit light [15][16][17]. Although weak ECL emission can also be directly generated from peroxydisulfate in aqueous solution without ECL luminophore [18][19][20], little sensing strategy has been developed with the ECL of pure peroxydisulfate.…”
