摘　　要：建立了离子色谱法测定火腿肠中的硝酸盐和亚硝酸盐含量的方法。利用纯水萃取火腿肠中的硝酸盐、亚硝酸盐,经过煮沸、冷冻、过滤后进样测定。经过多次实验,该方法样品加标回收率:硝酸盐99%～101%、亚硝酸盐96%～99%;标准曲线的相关系数分别为0.9990和0.9990。Establish a method of using ion chromatography to determine nitrate and nitrite in ham sausage. Use pure water to extract the nitrateand the nitrite. The samples was boiled,freezed and filtered The filtrates were de- termined directly by ion chromatography. After many determinations,the ratio of recoveries of this method ：Ni- trate 99 %-101%,nitrite 96 %-99 %;the correlation coefficients of the standard curve are 0.999 0 and 0.9990.
