摘　　要：在光照条件下（包括模拟太阳光和紫外光），４－氯酚溶液浓度随着光照时间的延长而降低，ＣＯ２的释放表明在４－氯酚光化学反应过程中存在矿化作用．通过光子相关光谱表征，确定反应体系存在聚合作用，聚合物具有荧光性．对反应体系进行ＵＶ、ＩＲ光谱表征，表明这一过程中存在腐殖化作用，有类腐殖质生成．聚合化与矿化相比较，前者是主要过程．Under irradiation of light (including simulated sunlight and UV light),4 chlorophenol(4 CP) concentration in aquatic solution decreased with irradiating time length.The release of CO 2 indicated that there was a mineralization during the process of photochemical reaction of 4 CP.Through the characterization of photo correlation spectrum,it was determined that there was a polymerization in the reaction system,the polymer was fluorescent.Through the characterization of UV,IR spectra for reaction system,it was considered that there was a humification during this process,humic substance like yielded.In comparison with mineralization,polymerization is a main process.
