报道了以２，４二硝基苯肼酸性饱和液吸收空气和废气中的醛和酮，所形成的腙衍生物以高效液相色谱分析。本法预处理回收率为９０％～１１０％，最低检则限为１～５ｎｇ，线性工作范围为５～３００ｎｇ。可测定空气和车间空气中的１０种醛和酮类污染物     

偏二甲肼污水的好氧生物降解及其动力学研究（英）

Unsymmetrical dimethylhydrazine （UDMH） is a main liquid rocket propellant. There are plenty of toxic and stable contaminations in its wastewater. The harmful influence has been considered. Nowadays the disposal technology of wastewater containing UDMH has plenty of disadvantages, such as high energy consuming, low safety factor, numerous secondary contaminations, strong toxicity, and so on. It is necessary to find a new way for wastewater disposal. Biodegradation technology is low innocuity and cleanliness, has great degradation capacity, and can almost degrade all kinds of organic substances. In this paper the aerobic active sludge is used to treat wastewater containing UDMH which is one kind of biodegradation technology.     

应用于环境样品预处理的新技术

本文对近年来发展起来的超临界流体萃取技术(SFE)和固相微量萃取技术(SPME)在环境样品预处理中的应用进行了介绍,并与传统的样品预处理方法进行了比较,指出了这两种新技术所具有的优势,并对其应用前景进行了展望。
