The color of each solution was expressed by Trichromatic Theory with the R, G, and B-values. Under optimum conditions, the R value gets increased proportionally to the concentration of Cu2+ in the range of 8.33 × 10−8−1.33 × 10−6 mol/L, and thus can be successfully applied ...

Under the illumination of 365 nm ultraviolet lamp, the color of the CBM solution changed from light blue to dark blue after the addition of Cu2+. The combination mechanism of CBM with Cu2+ was nicely explored by density functional theory studies. The probe CBM has good cell permeability, ...
TAA can detect Cu2+ and Hg2+ ions by different color changes from pale yellow to deep yellow and orange, respectively, in aqueous media. TAA differently binds to Cu2+ as a 1:1 ratio and Hg2+ as a 2:1 ratio. The detection limits towards both analytes turned out to be 0.08?μM for...
