摘　　要：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.
