| 摘 要： | 本文研究了用185nm UV和254nm UV照射方法降低高纯水中的TOC和废水中五种有机物的TOC,用185nm UV能有效地将高纯水中的TOC降低到(≤0.3μg/L),满足超大规模集成电路用水的需要.同时研究了用两种不同的紫外线185nmUV和 254nmUV,对比照射降低水中难生物降解的有毒、有害的五种有机污染物(二苯甲酮、孔雀石绿、对氯苯酚(4-CP)、对硝基苯酚(4-NP)和罗丹明B(Rh B)的TOC,结果表明185nmUV,比254nmUV,降低有机物的TOC好得多.有利于环境保护.

| Abstract: | The abatement of total organic carbon(TOC),in high purity water by using 185nmUV and 254nmUV irradiation was studied.By this photodegradation method,The TOC concentration in high purity water can be decreased to ≤0.3 μ g/L which meets the requirement for ULSI application.Besides,five kinds of waste water containing diphenyl keton,malachite green,4-chlorophenol(4-CP),4-nitrophenol(4-NP),or Rhodamine B(Rh B),were treated by 185nmUV or 254nmUV irradiation.Experimental data showed that these toxic organic pollutants,which are difficult to degrade by 254nmUV irradiation are easily degradable by 185nmUV irradiation. |
