Název v původním jazyce

Sensitized chemiluminescence in micellar mixtures of phthalhydrazide and selected dyes

Popis výsledku v původním jazyce

A simplified quantitative model of chemiluminescence intramicellar sensitization is proposed, based on the analytical solution of Forster's energy transfer function for donor-acceptor pairs residing on micellar spherical surface. To test the usability ofthe model, the intramicellar sensitization of phthalhydrazide chemiluminescent oxidation by energy transfer to several xanthene as well as non-xanthene dyes has been investigated. The reactions were initiated using three different initiation systems: copper sulphate-hydrogen peroxide system, sodium hypochlorite and hydrogen peroxide-sodium hypochlorite. In this work, we bring an experimental evidence that different transfer mechanisms operate, if phthalhydrazide-sensitized chemiluminescence reactions are initiated by copper sulphate-hydrogen peroxide, sodium hypochlorite or sodium hypochlorite-hydrogen peroxide. Only the latter system is selective enough to oxidize phthalic hydrazide much more rapidly than dyes employed as acceptors. T
