污水中可吸附有机卤素（AOX）的中子活化分析

Determination of Adsorbable Organic Halogen Compounds in Sewage by Neutron Activation Analysis

摘要: 可吸附有机卤素（AOX）是一项表征有机卤化物的国际性水质指标。建立了中子活化分析水体AOX的方法，对氯、溴、碘的检出限分别为60 ng、15 ng和6 ng。采用中子活化技术测定了某纸浆厂污水和医院污水可吸附有机卤素的含量，结果表明，纸浆厂和医院污水中的有机卤素污染问题不容忽视。

Abstract: Adsorbable organic halogen compound (AOX) is an international water quality index for organic halogens. In this paper, a method of determination of AOX in sewage water using neutron activation analysis was established. The detection limits for Cl, Br, I are 60 ng, 15 ng and 6 ng, respectively. In addition, the AOX content in sewage water of pulp mills and hospital was determined using neutron activation analysis. Results indicate that contamination of organic halogen compounds in sewage water of pull mills can not be ignored.
