摘要
文章依据酚二磺酸法测定硝酸盐氮的标准方法进行实验。通过大量实验证明,按"标准方法"进行测定废水中硝酸盐氮的含量存在着一定的误差。因此,文章从校准曲线的绘制和样品测定两方面进行改进和探讨,并经过国标考核样的验证,检验了改进方法的可行性。
In the paper,based on phenol disulfonic acid method of nitrate nitrogen standard method carry out such experiments.Through a large number of experiments show that by the "standard method" for determination of nitrate nitrogen must exist error.Therefore,the paper from the calibration curve and samples drawn both to improve and explore,and after examination GB kind of verification,testing to improve the feasibility of the method.
