Abstract
Upon mixing of oxovanadium(IV) acetylacetonate, this complex caused an increase in the chemiluminescence (CL) of luminol in a reverse micellar medium of cetyltrimethylammonium chloride in chloroform-cyclohexane (6:5 vlv)-water (buffered with NaOH-Na2CO3, pH 12.5) even in the absence of an oxidizing reagent such as hydrogen peroxide. In this CL process, the reaction of Luminol with the oxovanadium(IV) ion produced from the decomposition of the oxovanadium(IV) complex in the reverse micelles is probably significant. A flow-injection method for the oxovanadium(IV) determination based on the present reversed micellar mediated CL reaction was examined. All the analytical conditions were optimized using the sample solution of oxovanadium(IV) acetylacetonate in chloroform. A detection limit (DL) of 0.1ng cm-3 and a linear calibration graph was obtained with a dynamic range from the DL to 50ng cm-3.Keywords
