摘要
水溶矿,分离水不溶物后滤液,在紫外光谱区,硝酸根有强烈的吸收,其吸光值与硝酸根的浓度成正比。方法快捷简单干扰小,准确度高、灵敏度高、精密度好。
Water-solubility mine, filtrate after separated not water-solubility substances, in UV spectral area, nitrate with strongly absorbency, its absorptivity and concentration of nitrates are in direct proportion. This method is shortcut, simple, mini- mized intervene, higher accuracy, sensitivity and exact.
