矿泉水中的亚硝酸盐分析

In the natural world, in general, nitrite ion is widely distrilbuted in environment at a low concentration and its balance ismaintained in the nitrogen cycle. However, due to the excessive use of fertilizers and inappropriate treatment of famanimal wastes, peroxynitrite ion is entering groundwater. As a result, the levels of nitrite ion in natural and well watersare tend to be high. This time, the nitrite concentration in mineral water was analyzed and it was found to be 0.20 mg/l(should be 10 mg/L or less according to the water quality standard ). The 6-cell turret in U-5100 switches the cellsautomatically and therefore, by the combined use wth the reagent for the simple analysis, the high throughput analysiscan be performed easily.
