Chemiluminescence Energy Transfer Reaction for the On-Line Preparation of Peroxymonocarbonate and Eu(II)−Dipicolinate Complex

Abstract

In this work, an on-line preparation of peroxymonocarbonate was formed innovatively, which offered a reliable intermediate for further investigation. The forming conditions of on-line peroxymonocarbonate ions were investigated in detail. Meanwhile, the energy transfer chemiluminescent reaction of peroxymonocarbonate and the Eu(II)-dipicolinate complex was studied. Through UV-visible absorption spectra, CL method, ESR spin-trapping technique, and mass spectrum experiments, it can be concluded that peroxymonocarbonate oxidizes Eu(II) to Eu(III), and simultaneously creates radicals. The bond rearrangement within radicals formed the singlet molecular oxygen. The energy originating from the singlet oxygen was accepted by the (Eu(III)dipic) -complex. The excited (Eu(III)*dipic)-ions underwent radiative deactivation and emitted the chemiluminescence. The peroxymonocarbonate system was a simple, inexpensive, and relatively nontoxic alternative to other oxidants, and it can be used in a mild, neutral-pH environment.

Controlled leaching with prolonged activity for Co–LDH supported catalyst during treatment of organic dyes using bicarbonate activation of hydrogen peroxide

“…4C, it is clear that CoMgAl-4 catalyst showed the lowest catalytic activity both with H 2 O 2 and bicarbonate alone, but its activity significantly increased by the addition of H 2 O 2 together with bicarbonate. This enhanced activity of catalyst together with H 2 O 2 and bicarbonate suggested hydrogen peroxide activation produces different reactive oxygen species, such as • OH, singlet oxygen, superoxide, carbonate anion radical, and a prominent peroxymonocarbonate [14][15][16][17][18][29][30][31].

Study on the generation mechanism of reactive oxygen species on calcium peroxide by chemiluminescence and UV‐visible spectra

“…Furthermore, CL is an effective method in research on ROS, because of the associated instantaneous nature of CL and the short lifetime of ROS radicals (11)(12)(13)(14)(15)(16). Goto et al (17) successfully investigated the CL mechanism of the alkalineearth metal peroxides (MgO 2 , BaO 2 ) with CL reagents (luminol and lucigenin), and demonstrated that the hydroxyl ( • OH) and • O 2 − were released chiefly on the MgO 2 and BaO 2 , respectively, with CL.…”

Determination of halofantrine and its main metabolite desbutylhalofantrine in rat plasma by high‐performance liquid chromatography with on‐line UV irradiation and peroxyoxalate chemiluminescence detection

“…Chemiluminescence (CL) is a powerful analytical technique that has excellent sensitivity and wide linear dynamic range (Lin et al, 2001;Liu et al, 2006) and can be used in the determination of different 102 compounds in a lot of matrices depending on their participation in the CL reaction as precursors, catalysts, inhibitors, oxidants, etc. Among the different CL systems that can be used for analytical purposes, peroxyoxalate (PO) reaction is probably the most versatile and efficient (Brinkman, 1987).…”
