| 英文摘要 | Most electrochemiluminescence (ecl) systems require high concentrations of quencher to totally quench ecl. in this study, we found that ozone can quench tris(2,2'-bipyridyl)ruthenium(ii) ecl using formaldehyde, methylglyoxal, or glyoxalate as co-reactants at a glassy carbon electrode with remarkable efficiencies even when the concentration of ozone is merely 0.25% of that of the co-reactant. the strongest quenching is observed with the tris(2,2'-bipyridyl)ruthenium(ii)/formaldehyde ecl system. the tris(2,2'-bipyridyl)ruthenium(ii)/formaldehyde ecl intensities decrease linearly with the ozone concentration over the range of 0.025-25 mu m (r = 0.9947) with a limit of detection of 8 nm. the method is more sensitive and faster than most methods. it shows high selectivity in the presence of other ros or oxidants and some metal ions, such as h2o2, clo-, mg2+, ni2+, etc. the method exhibits high recoveries for the detection of ozone in a ventilated photocopy room. |
