本试剂盒适用于水中硝酸根离子（NO₃⁻）的紫外比色法测定。其原理基于NO₃⁻与NO₂⁻在210～220 nm紫外区均具特征吸收峰，且浓度与吸光度呈线性正比关系，据此可直接定量NO₃⁻含量。样品中NO₂⁻的干扰可通过加入氨基磺酸分解去除；其他有机物干扰则通过测定275 nm处吸光度并乘以校正因子进行校正。
This kit is suitable for the ultraviolet colorimetric determination of nitrate ions (NO₃⁻) in water. The principle is based on the fact that both NO₃⁻ and NO₂⁻ exhibit characteristic absorption peaks in the ultraviolet region of 210–220 nm, and their concentrations are linearly proportional to the absorbance, thereby allowing the direct quantification of NO₃⁻ content. Interference from NO₂⁻ in the sample can be eliminated by the addition of sulfamic acid to decompose it; interference from other organic substances is corrected by measuring the absorbance at 275 nm and multiplying by a correction factor.
