The reactivity of ozone and hydroxyl radical with the seven organic fractions fractionated by resins was examined. The fractions of hydrophobic acid and transphilic mainly caused the initial ozone consumption. The first order reaction rate constants of ozone with seven fractions after 1min. reaction ranged from 1.4 to 3.9x10^<-4>sec.^<-1>, which were relatively comparable. OH radical may be produced through the reaction of ozone with the fractions of hydrophobic acid, transphilic, hydrophobic neutral and hydrophilic neutral.

考察了臭氧和羟基自由基与树脂分离的七种有机组分的反应性。初始臭氧消耗主要由疏水酸和亲脂酸组成。测定了臭氧与七种组分在1 min后的一级反应速率常数。反应范围为1.4至3.9 × 10 - <-4>6秒。<-1>，这是相对可比的。臭氧与疏水性酸、亲脂性酸、疏水性中性酸和亲水性中性酸反应产生OH自由基。
