Figure 6. Test strips.

Figure 6

(a) Photos of fluorescence response of TPE-S test strips exposed to different concentrations of Hg2+ ions in water, then dried in air. From left to right: single TPE-S test strip; TPE-S test strips with different concentration of Hg2+ ions: 1 × 10−7, 1 × 10−6, 1 × 10−5, 1 × 10−4, 1 × 10−3 M. (b) Photos of colorimetric response of TPE-S test strips exposed to different concentrations of Hg2+ ions in water, and then dropped some t-BuOK (saturated solution in t-butanol). From left to right: single TPE-S test strip; TPE-S test strips with different concentration of Hg2+: 1 × 10−7, 1 × 10−6, 1 × 10−5, 1 × 10−4, 1 × 10−3 M.
