本文应用离子色谱法测定了矿泉水、纯净水中F~-、Cl~-、NO_3~-、SO_4~(2-)等阴离子,结果表明,利用该法测定以上阴离子,速度快,方法简便,能一次同时测定多种离子,获得准确可靠的定性和定量结果。
In this paper, the anions of F ~ -, Cl ~ -, NO_3 ~ -, SO_4 ~ (2-) in mineral water and pure water were determined by ion chromatography. The results showed that the above method can be used to determine the above anions with high speed, A variety of ions simultaneously measured at one time, to obtain accurate and reliable qualitative and quantitative results.
