氨氮检测几种常见的方法比较,你了解吗?

发布日期:2019-09-19 00:00 来源:http://wkbbxqnf.com 点击:

 水体中的氨氮主要以铵盐和游离氨形式存在。水体中的氨氮主要来自于生活污水和含氮工业废水的排放、农业施肥灌溉排水、动物的排泄物和动植物腐烂过程、水体流经含氮矿物层溶解的氨氮化合物等,水质气体检验检测,另外化石燃料燃烧和汽车尾气排放到大气中的氮氧化物也会转化成硝酸等含氮化合物,通过雨水淋洗作用进入地面水体。分析水体中氨氮含量有助于了解水体的污染情况,掌握水体中氨氮的变化趋势以及采取相应的治理措施。近些年随着水质检测要求的提高,水体中氨氮的检测方法也越来越精细,分光光度法和电极法是常用的两大类检测方法,本文对水体中几种常用的氨氮检测方法进行了比较分析,以为相关工作人员提供有益参考。
