Zhu, Yinggui published the artcileElectrogenerated chemiluminescence behavior of Tb complex and its application in sensitive sensing Cd2+, Safety of Pyridine-3-sulfonic acid, the publication is Electrochimica Acta (2017), 1-8, database is CAplus.
The authors report a novel rare earth metal complex with the weak ligand of aromatic sulfonic acid (pyridine-3-sulfonic acid, 3-pSO3H), and characterized by FTIR, UV-visible, energy-dispersive x-ray spectroscopy (EDX), electrochemiluminescence spectra, etc. Then an excellent electrochemiluminescence (ECL) signal was observed with K2S2O8 as the coreactant in NaAc-HAc buffer solution For another thing, the electrochem. properties of the compound were thoroughly studied in MeCN solution, the possible ECL reaction mechanism is proposed as well. Also, a simple and straightforward ECL platform is reported for sensitive and selective detection of Cd2+ due to the effective quenching after addition of Cd2+. Other heavy/transition metal ions do not interfere with the sensing. The limit of detection is determined as 0.13 nM, the results suggested that as-prepared complex could be a promising material for developing ECL sensors to detect the Cd2+ rapidly indwell in environmental and practical samples.
