Figure 9

UV absorption spectra of activated liquids for 1.0, 5.0, 30.0, and 60.0 min. (a,c,e,g,i) represent the deep UV absorption spectra of tap water, deionized water, distilled water, filtered water, and 0.9% saline solution that were activated. (b,d,f,h,j) represent the near UV absorption spectra of tap water, deionized water, distilled water, filtered water, and 0.9% saline solution that were activated with the pattern of HNO2 formation.
