pubmed:abstractText |
CdTe quantum dots (QDs) were modified with thioglycolic acid (TGA) and synthesized in aqueous medium. The optimum fluorescence intensity was found to be at pH 6.24 with a CdTe QDs concentration of 4.96 x 10(-7) mol L(-1). The quenched fluorescence intensity of CdTe QDs is linearly proportional to V(V) concentration from 10 to 200 ng mL(-1) with correlation coefficient R = 0.9985. The limit of detection for V(V) was 2.07 ng mL(-1). The proposed method was successfully applied to the analysis of trace amounts of V(V) in water samples with recovery of 96.5-101.8%, and the results were in good agreement with those of electrothermal atomic absorption spectrometry.
