摘要
采用离子色谱法测定了水样中硝酸盐氮和亚硝酸盐氮含量。结果表明,校准曲线线性相关系数高,并且能在很大范围内呈现线性。运用该方法实测标样和水样,精密度和准确度都能满足需求,表明该方法测定结果可靠,具有一定的应用价值。
Nitrate nitrogen and Nitrite nitrogen content of water were determined by national standard method. The result showed that the correlation coefficient R of the calibration curve was high, with a large range of linearity. The accuracy and preciseness of this method both can meet the needs in standard and sample determination, which indicated that this method was reliable and suitable, and had some application values.
