海水中的常见元素对过硫酸钾消解海水中总氮测定(紫外分光光度法)的影响
摘要:本文选取海水中常见元素作为研究对象,考察它们对海水中总氮测定(紫外分光光度法)的影响情况,研究结果表明:1)所选取的常见元素中HCO3-、Br-、Fe3+、Cr6+对测定有影响;2)ρHCO3- 在0.142g/L~1g/L范围内,HCO3-离子对海水中总氮测定的影响程度随HCO3-离子浓度的增加先减小后增大;3)ρBr-在0.0674g/L~0.3g/L范围内,Br-离子对海水中总氮测定的影响程度随离子浓度的增加而减小;4)ρFe3+在0.5125g/L~2.05g/L范围内,Fe3+离子对海水中总氮测定的影响程度随离子浓度的增加先增大后减小;5)ρCr6+在0.52g/L~2.08g/L范围内,Cr6+离子对海水中总氮测定的影响程度随Cr6+离子浓度的增加先减小后增大。实验结果为消除海水中总氮测定的干扰因素提供了参考。

The Effect of Common Elements in Seawater to TN Test by Potassium Persulfate Digestion (UV Spectroscopy)
Abstract:
The researcher selected some common elements/ions in seawater, to evaluate the affect to TN testing by UV Spectroscopy.
The results show that:
1)Among the common elements selected, HCO3-、Br-、Fe3+、Cr6+ affect TN testing.
2), the effect of HCO3- to testing increases fist, then decreases along with the increasing of concentration within the range of 0.142g/L to 1g/L.
3), the effect of ρBr- to TN testing decreases along with the increasing of its concentration within the range of 0.0674g/L~0.3g/L.
4), the effect of Fe3+ to TN testing increases fist, then decreases along with the increasing of concentration within the range of 0.5125g/L~2.05g/L.
5)the effect of Cr6+ to TN testing decreases fist, then increases along with the increasing of concentration within the range of 0.52g/L~2.08g/L.
the research results aim to provide reference for interference elimination of seawater TN testing.  

Key words: common elements, UV, Potassium persulfate digestion, spectrum scanning
