随着化学工业的迅速发展,硝基苯和硝基氯苯广泛地应用在农药、染料等工业,且排放量较大,给江河带来严重的污染,对人和动物毒性很大,会损害人和动物的内脏。因此,对江河水中硝基苯和硝基氯苯的监测是十分必要的。我们采用国产高分子微球 GDX—502为吸附剂[1],以乙醚为洗脱剂,富集了第二松花江水中 ppb 级的硝基苯和硝基氯苯;并利用电子捕获鉴定器,以己二酸乙二醇
With the rapid development of the chemical industry, nitrobenzene and nitrochlorobenzene are widely used in pesticides, dyes and other industries, and the emissions are large, causing serious pollution to the rivers, causing great toxicity to humans and animals and impairing Internal organs of humans and animals. Therefore, the monitoring of nitrobenzene and nitrochlorobenzene in river water is very necessary. We use domestic polymer microspheres GDX-502 as adsorbent [1], with ether as eluent, enriched in the second Songhua River ppb nitrobenzene and nitrochlorobenzene water; and the use of electron capture to identify To ethylene glycol adipate
