摘要
本文研究了硝基氯苯(邻、间、对位)在纯水及江水中的光化学分解。结果表明光化学反应均属表观动力学一级反应。从它们在纯水(氙灯下)、纯水(300—400nm光照下)、纯水(阳光下)、天然水(阳光下)中分解的速度常数来看,pH、腐殖质、硝酸根对光解影响较大,无机盐对光解无显著影响,硝基氯苯在pH>6的纯水中光解有中间产物生成。
The photodegradation of nitrochlorobenezens(o,m,p) in pure water and river water were studied. These photodegradation reaction all were dynamic first-order reaction. The rate con-stantsof photolysis of nitrochlorobenzene in pure water(Xenon lamp),pure water(300-400 nm rays),pure water (sun light) and natural water(sunlight) were determined. The effects of pH, humic substances, nitrate and inorganic salt on photodegradation of nitrochlobenzene in aqueous solution were studied in the laboratory with artificial(Xenon lamp) sunlight.
