Abstract
New heterogeneous chemiluminescence(CL)reaction media based on barium oxide(BaO)CL reaction system were developed using peroxomonosulfate(KHSO5)and hydrogen peroxide(H2O2)and nitrite(NO2-).It is known that KHSO5, an oxidizing agent, is decomposed by a metal ion catalyst(Co2+)to yield reactive species(Co3+, SO4-, etc.), which are strong oxidizing agents.On the other hand, peroxynitriteONOO- and nitrogen dioxide radical(NO2)obtained by reaction between H2O2 and NO2- are also powerful oxidizing agents.We have thus tried to immobilized these active species on the surface of BaO in order to improve the capabilities of BaO as not only CL, but also various reaction media.
