五氯酚钠在水体中的光解

旨在探讨各种要素对五氯酚钠光解的影响。室内紫外光照射实验表明，五氯酚钠溶液的浓度，体积，ｐＨ值，受光面积以及光照距离等，均对光解速率、洮解历时或半衰期产生明显的影响。室外太阳光照射试验结果表明，五氯酚钠试样光解受季节影响显著，春季的光解速率常数为冬季值的１０倍。

A Study on Photochemical Degradation of Na-PCP in Aqueous Solution

odium pentachlorophenate(Na-PCP),a kind of chemicals,has a harmful effect on water quality while photochemlcal degradatlon is a main forin of its degradations in nature, This paper discusses the effects of some factors on photochemical degration of Na-PCP. The ultraviolet irradiation experiments in laboratory show that the distance from the light source, the irradiated area,and concentration as well as the volume and pH of Na-PCP aqueous solutions have obvious effects on the half-life and duration of photochemical degradation of Na-CP. Sunligth irradiation experiments show that the photochemical degradation of Na-PCP is affected by seasons,while the degradatlon rate appears to be tenfold larger in spring than in winter.
