Hydrogen-Bonding Recognition-Induced Colorimetric Determination of Hydrazine Based on the Tryptophan Capped Gold Nanoparticles

Figure 7

The relative UV-Vis absorbance spectra of reaction solution in the presence of different concentrations of hydrazine (the hydrazine concentration from a to f: 7.57 × 10−6, 2.01 × 10−5, 7.57 × 10−5, 2.01 × 10−4, 7.57 × 10−4, and 2.01 × 10−3 M) under the optimum conditions. Insert: the liner correlation between the absorption ratio A540 and the hydrazine concentration.
