Flow Chemiluminescence Determination of Antimony(III,V) Using a Rhodamine B-Cetyltrimethylammonium Chloride Reversed Micelle System Following Liquid-Liquid Extraction

“…10 In order to extend the use of the CL method for practical analysis, on the other hand, rhodamine compounds as a series of xanthene dyes are attracting increasing attention as highly sensitive and selective CL reagents. As is well known, rhodamine B (RB) has been applied in analytical chemistry, 11,12 mostly in spectrophotometry 13 and fluorescence analysis.…”

Chemiluminescence from an Oxidation Reaction of Rhodamine B with Cerium(IV) in a Reversed Micellar Medium of Cetyltrimethylammonium Chloride in 1-Hexanol-Cyclohexane/Water

“…As is well known, rhodamine compounds, as a series of xanthene dyes, have been applied in analytical chemistry, 21,22 especially in spectrophotometry 23 and fluorescence analysis, 24 and have also been used as CL reagents recently. 25 Although rhodamine B (RB) was often considered to be a sensitizer for the CL systems, 26,27 it was reported that CL emission could be generated by the oxidation of RB.…”

Photophysical pathways in metal complexes

“…Spectroscopic methods directly count the number of acceptor excited states formed by their luminescence rather than by chemistry. *D + A -D + *A 0et (15) *A^A + hv (17) Acceptors have included Cr(III) complexes ( 22) and more recently laser dyes (23,24). The laser dyes can have advantages over the Cr(III) complexes.…”
