| 摘 要： | 目的建立同时测定肉及肉制品中亚硝酸盐、硝酸盐的离子色谱法。方法把肉及肉制品进行简单的提取后,以碳酸钠-碳酸氢钠为淋洗液,阴离子交换柱分离,电导检测器检测,保留时间定性,峰面积定量。结果样品中亚硝酸盐、硝酸盐的最低检测浓度均为0.15 mg/kg,相对标准偏差均在1.51%以下,回收率在87.60%以上。结论该方法操作简单,重复性好,回收率、灵敏度均达到检测的要求。

| Abstract: | Objective]To establish a method for simultaneous determination of nitrite and nitrate in meat and meat products by ion chromatography. Methods]After simple extraction of meat and meat products,nitrite and nitrate were separated on a anion exchange column with sodium carbonate-sodium bicarbonate as the eluent,then detected by electrolytic conductivity detector,quantified by peak area and qualitatively measured by its retentive time Results]The minimum detectable concentration of nitrite and nitrate was bo... |
