| 摘 要： | 在用Aqualab中性载体电极监测水体中的氨氮时,水体中的钠、镁、钙3种离子在离子浓度较大时会产生干扰,但一般地表水中浓度不高,可以忽略。而钾离子干扰较大,如水体中含钾离子,则要考虑消除干扰。

| Abstract: | When there are high contents of natrium ion and magnesium ion and calcium ion in the water, these ions will disturb the determination of ammonia nitrogen by using Aqualab ammonia nitrogen determination apparatus. Sometimes the interference will be neglected in the normal surface water. But the interference from the potassium ion cannot be ignored. So it is necessary to remove the interference. |
