Taispoh IKEURA was using simple sampler to measure the concentration of Ozone by florescent intensity of p-Acetamidophenol solution after sampling. p-Acetamidophenol was oxidized by Potassium ferricyanide in buffer solution. In the process of oxidation, p-Acetamidophenol may become diemer or trimer and polymer. To identify structure of compound(DDAP), to analyze the florescent intensity of DDAP, in order to get a formula using to measure the concentration of ozone in atmosphere. Using different oxidants( Potassium ferricyanide,Hydrogen peroxide ) can get DDAP after reaction. The melt point of DDAP has great difference to records. We can confirm DDAP is dimmer by analyze of IR and NMR and Mass. DDAP recrystallise from MeOH and dissolve in buffer solution. We can get an equation after analyzing florescent intensity. FI(L)＝39.6【μM】DDAP＋12.6 Compare with the florescent intensity measured by simple sampler and concentration of ozone from atmospheres monitor station. A useful equation to get concentration of ozone can be obtained. O3(μM)＝ ， O3(ppb)＝ 。The florescent intensity of 1 mole concentration of ozone is 0.59 times amount of 1 mole DDAP. 39.6 (FI(L,sampling))/0.5919-12.6 (FI(L,sampling))/0.5919-12.6 2.122
