The gradient elution is reasonable when the retentiontime is 2.3 times after the appearance of prominent peak with initial mobile phase acetonitrile-water (40:60).
用初始流动相乙腈-水(40:6 0)洗脱至主峰出峰保留时间的2.3倍时开始进行梯度洗脱比较合理。

The effects of applied voltage, retentiontime and initial concentration on decomposition efficiency were studied and the decomposition products of ammonia were analyzed.
