利用快速定氮仪测定废水中的氨氮

含氨废水通过 NC2定氮装置将氨分离、吸收、滴定集为一体 ,克服了传统全量蒸馏装置或半微量蒸馏装置将废水中的氨分离、吸收、定容分步进行的复杂、耗时缺点 ,从而达到快速测定废水中氨氮含量的目的。文中介绍 NC2定氮装置及分析操作方法

Determination of ammonia-N in the waste water by rapid azotometer

In a traditional total quantity distillation setup or a half microdistillation setup, the separation and absorption of ammonia and constant volume must be done separately, so the analyzing program is complex and needs long analysis time. By the rapid azotometer (Type:NC2), the ammonia in the waste water could be analyzed through one step which includes separation, absorption and titration. Compared with the tradition analysis methods, the ammoniaN in waste water can be analyzed more quickly. The setup of NC2 azotometer and analyzing operation method are stated.
