改进分光光度法测定水中硝酸盐氮的前处理方法

Improvement of Measure Nitrate Nitrogen Precondition Method in Water Sample by Spectrophotometry

使用粉状活性碳代替树脂吸附处理污水水样,改进分光光度法测定硝酸盐氮的前处理方法,不仅省时省力,简便快速,且方法切实可行,完全能满足环境监测分析质量要求。

Improve method of measurement nitrate nitrogen precondition by activated carbon replaced synthetic resin preliminary treatment. The method saved time and labourforce, that was simple, speed doable and satisfied environmental monitoring analytic quality needs.
