DETERMINATION OF HYDROXYL RADICALS IN AQUATIC ENVIRONMENT WITH A NEW MOLECULAR PROBE

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.
