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.
