摘要
考察3种商品纳氏试剂在地表水氨氮分析中的适用性。研究了纳氏试剂在不同显色时间和加入量下的使用效果,得出3种商品纳氏试剂的最佳使用条件。通过检出限试验、实际地表水样测定以及加标回收试验对商品纳氏试剂进一步筛选,确定了适合地表水氨氮分析的纳氏试剂,并为商品纳氏试剂的可靠性提供了可行的检验方法。
The applicability of ammonia nitrogen determination in surface water by 3 commercial Nessler reagents was evaluated.The using effect of Nessler reagent under different chromogenic times and dosages was investigated,and the optimum working conditions of 3 commercial Nessler reagents were obtained.The detection limit test,determination of actual surface water and recovery test were applied for the further selection of commercial Nessler reagents.The most suitable Nessler reagent for ammonia nitrogen determination in surface water was ascertained,and the feasible test method for the reliability of commercial Nessler reagent was also provided.
