浅谈絮凝沉淀法和离心机沉淀法在氨氮测定中的比较

摘要

In order to shorten the time and accuracy of measurement of ammonia nitrogen waste water,using centrifuge supernatant obtained by centrifugation and suspended solids precipitation flocculation carried out a series of controlled trials,after several tests,it was confirmed centrifuge precipitation indeed shorten the test of time,both accurate and fast and very suitable for ammonia analysis.%为了缩短污水氨氮测定的时间及准确性，采用离心机的离心悬浮物沉淀取得上清液及絮凝沉淀进行了一系列的对照试验，经过多次试验，证实了用离心机沉淀法的确缩短了化验的时间，既准确又快捷，非常适合氨氮分析。
