摘要: 采用水杨酸分析水体中羟基(OH)的分子探针, 测定了紫外光照下NO3- 和NO2-体系中OH的稳态浓度和量子产率, 并在此基础上估算了天然水体中OH自由基的生成速率和清除有机污染物的速率.

Abstract: In this paper,salicylic acid was used as a molecular probe to determine hydroxyl radicals in aquatic system.The steady state concentrations and quantum yields of hydroxyl radicals formed by ultraviolet irradiation of nitrate and nitrite solutions were explored.Formation rate of hydroxyl radicals and removal rate of organic pollutants through oxidation with hydroxyl radical in natural water were estimated on the basis of above results.
