三聚氰胺装置废水中氨含量的蒸馏法测定

Determination by Distillation of Ammonia Content in Wastewater from Melamine Unit

在磷酸盐缓冲溶液中加热蒸馏三聚氰胺废水样品,逸出的氨被吸收后通过酸碱滴定测定其含量。该 方法抗干扰能力强,准确度高,完全能满足监测三聚氰胺装置废水中氨含量的需要。

The melamine wastewater sample is distillated in the phosphate buffer solution, the emitted ammonia is absorbed, and its content is determined by acid-alkali titration. This method provides a high degree of interference protection and high accuracy, fully meeting the requirements of monitoring the ammonia content in the wastewater from the melamine unit.
