中文摘要:
      通过对国产和进口NH+4、NO-3检测探头技术性能指标的测试,分析国产和进口水质NH+4和NO-3监测设备技术性能,确定其适应范围。比较两种仪器对单一纯溶液、复合溶液,以及多种实际水样的准确性和稳定性测试结果,得知两种仪器测定标准溶液及实际水样中NH+4和NO-3的标准值、实测值都具有较好的一致性,测量结果稳定性较好。国产仪器在≥500 mg/L的NO-3条件下误差较大,需稀释后测定,在其他常规质量浓度范围内完全可代替进口仪器,两种仪器均可用于不同环境水体的水质监测。
英文摘要:
      The technical functions of domestic and imported NH+4/NO-3 monitoring equipments and their adapting scope were developed by testing the technical performance indexes of NH+4/NO-3 detection probe. Comparing the accuracy and stability of the two equipments in applying to single standard solution, multi standard solution and practical samples, the results were consistent and stable. Domestic equipment had relatively large relative deviation when NO-3≥ 500 mg/L, dilution was needed before measuring, while in conventional mass concentration range, it could replace imported equipment. Both equipments could be applied to different water environment.
