摘要:
研究应用氨气敏电极对工业废水中氨氮进行测定时,pH值、电极响应时间、氨逃逸时间,以及废水中干扰物对氨气敏电极的电极电位的影响.结果表明,当pH值大于11时,pH值对测定电极电位没有影响; 氨浓度越高,电极响应时间越短,氨逃逸时间越迟; 氨气敏电极具有很高的选择性,在强碱性条件下,采用EDTA作掩蔽剂,13种干扰物质对测定没有明显干扰.
Abstract:
The effects of pH,electrode response time,ammonia escape time and chaff in waster water on electrode electric potential were investigated when determining content of ammonia nitrogen in industry waste water through ammonia electrode.It′s indicated that pH value has no effect on electrode electric potential when pH>11 and the higher the ammonia concentration,the shorter the electrode response time,the later ammonia escape time was.
