甲醛法测定化肥厂排放水中的氨

Determination of Ammonia in Discharge Water from a Chemical Fertilizer Plant by Formaldehyde Method

根据铵盐能与甲醛完全定量反应的原理 ,采用甲醛法测定化肥厂界区排放水中的氨。该方法干扰小 ,精密度高 。

In line with the principle that ammonium salt can reactquantitatively with formaldehyde, the formaldehyde method is used to determine ammonia in the discharge water from the battery limits of a chemical fertilizer plant. The method shows little interference and high precisionand is quick and accurate in determination.
