General description
Reflectoquant 硝酸盐试纸可用于快速测定水和水果/蔬菜中的硝酸盐含量，以帮助确定用于特定产品（例如婴儿食品）的给定交货批次产品是否可以发货。在试纸上，硝酸根离子被还原剂还原为亚硝酸根离子。在酸性缓冲液的存在下，这些亚硝酸根离子与芳香胺反应形成重氮盐，它继而与 N-（1-萘基）-乙二胺反应形成红紫色偶氮染料，该染料在RQflex® 20上通过反射法测定。为了在使用该定量方法之前以经济快捷的方式对样品进行预测试，以检查亚硝酸盐的干扰或估算硝酸盐的浓度以及可能的稀释系数，我们建议使用我们的半定量 MQuant 硝酸盐和亚硝酸盐试纸。进一步的定量测定方法可以在我们的Spectroquant测试上找到。
方法：试纸反色法 5 - 225 mg/l NO₃⁻ Reflectoquant®
Application
Nitrate Test Strips are used:
- To monitor nitrate levels in water treatment processes. This is crucial for preventing excessive nitrate concentrations, which can lead to environmental pollution.
- In the agricultural industry to analyze soil nitrate levels, aiding in the optimization of fertilizer use and improving crop yields.
