本实验通过对离子色谱条件进行优化，建立了离子色谱法测定生鲜乳中硫氰酸根的检测方法。浓度在0.1～5.0 mg/L，硫氰酸根标准曲线的线性相关系数为0.9993，方法检出限为1.3μg/L，定量限为4.2μg/L。对样品进行加标回收实验，硫氰酸根的回收率为95%～104%，RSD为0.9%～1.5%（n=6），该方法简单可靠，重现性好，适用于生鲜乳中硫氰酸根的检测。

The conditions of ion chromatography were optimized to establish the determination method of thiocyanate in raw milk by ion chromatography.In the range of 0.1 ~5.0 mg/L,the method had good linearity (R=0.9993),the method detection limit was 1.3μg/L,and the quantitative limit was 4.2μg/L.Thiocyanate recovery was between 95% ~104%,RSD was between 0.9%~1.5%(n=6).The method was effective and convenient,which could be adopted in thiocyanate determi-nation in raw milk.
