| Abstract: | The RPHPLC method was applied to the analysis of main composition of working liquid producting hydrogen peroxide by anthraquinone. EAQ, H 4EAQ, heavy aromatic hydrocarbon and trioctyl phosphate were sparated on a C 18 reversedphase column with an 67% aqueous methanol as the eluting agent, detected by UV. The optimal UV wavelengths were discussed. The relationship between EAQ, H 4EAQ peak area and amount in range of 16～160 ng(24～240 ng) was positively related(γ=0.9997 and γ=0,9994). The recovery of EAQ, H 4EAQ detecting were 99% above. |
