Colorimetric Detection of Ammonia Using Synthesized Silver Nanoparticles from Durian Fruit Shell

Figure 3

The effect of ammonia on the green fabricated silver nanoparticles; different levels of ammonia were added to the colloidal solution of Ag NPs containing a constant level of the nanoparticles (a). Change in the UV-visible spectra of silver nanoparticles as a function of different concentrations of ammonia from 0 to 3000 ppm (b). Plot of absorbance versus ammonia concentration (c).
