摘要
描述了蒸馏法测定氨氮时经常遇到的问题,提出了使用改进了的蒸馏装置对水样进行蒸馏预处理,在合理控制pH的前提下,所得数据具有较高的精密度和准确度.
This paper described problems often encountered in the ammonia nitrogen determination by using distillation method. Under the reasonable control of pH and by using an improved distillation unit to pretreat water samples, the result gave a high precision and accuracy.
