n this Article, we discovered several errors in wrongly combining some graphs and equations in Figure 7. This led
Figure 7. Dose−response graphs during detection of (a) Cr3+ in the range from 1 × 10−6 to 1 × 10−3 mol/L and (c) Cr2O72− and (e) CrO42− in the range from 1 × 10−6 to 2 × 10−3 mol/L (I0 and I are the luminescent intensities of 3 in the absence and presence of Cr3+, Cr2O72−, and CrO42−, respectively) and linear relationships at low concentrations of (b) Cr3+, (d) Cr2O72−, and (f) CrO42− in the range from 1 × 10−7 to 1 × 10−6 mol/L.
to the incorrect detection limits for Cr2O72− and CrO42−. Thus, parts d−f of Figure 7 and the related expressions are incorrect. Because all of the data in Figure 7 are original and correctly treated, the conclusions drawn in our Article are not influenced by these errors. However, the following corrections are required.
