Abstract: 目的 建立液相色谱-原子荧光光谱法测定淡水鱼中无机砷[AS(Ⅲ),AS(Ⅴ)]的方法。方法 准确称取鱼肉1.0 g,用0.15 mol/L硝酸于60℃超声提取40 min,加正己烷除去杂质后经0.45μm有机滤膜过滤及C18小柱净化。采用Hamilton PRP X-100阴离子交换柱(150 mm×4.1 mm,10μm)分离,磷酸氢二钠和磷酸二氢钾(pH=4.0)为流动相等梯度洗脱,流速1.3 ml/min,用原子荧光检测。保留时间定性,外标法定量。结果 2种砷形态线性关系良好(r>0.999),方法检出限AS(Ⅲ)为0.017 mg/kg,AS(Ⅴ)为0.050 mg/kg。平均回收率为85.4%~103.8%,精密度为1.1%~3.4%。结论 本方法操作简便、结果准确、精密度高,适用于同时检测淡水鱼中2种形态的无机砷AS(Ⅲ)和AS(Ⅴ)。
