用间苯二酚对天然水中痕量亚硝酸根的荧光光度测定,方法简便、快速。检出下限为5.8×10~(-9)g/ml。用0.26ppm亚硝酸根测定,其相对标准偏差为±2.0％。
Resorcinol in natural water with trace nitrite fluorescence spectrophotometry, the method is simple and fast. The detection limit was 5.8 × 10 ~ (-9) g / ml. The relative standard deviation was 0. 2.0% with 0.26 ppm nitrite.
