中文摘要: 以液相色谱-原子荧光联用技术为检测手段，在现有国标检测方法的基础上，研究一套检测动物性水产品中 无机砷含量的样品前处理方法。该方法以超声提取为主要手段，被测样品经均质后，在 60 ℃下超声提取 60 min，检测 结果与国标法测定结果之前的相对误差为 3.2 %，，方法检出限为 0.01 mg/kg， 0～50 μg/L 浓度范围内线性良好，回收 率为 89.6 %～93.2 %，相对标准偏差（RSD）为 1.07 %～5.57 %，准确度、精密度均满足方法学要求。该法具有操作便捷、 干扰少、准确度好等优点，适用于批量水产品种无机砷的测定。

Abstract:A sample pretreatment method to detect inorganic arsenic in aquatic products of animal origin is de－ veloped. In this method， the objective is obtained by using extracted ultrasonically at 60 ℃ for 60 min. The ex－ perimental results show that the relativeerror is less than 3.2 % against the national standard method.The limits of detection were 0.01 mg/kg， and the recoveries of standard addition were 89.6 %-93.2 %， respectively. The relative standard deviations（RSD） of this precision were 1.07 %-5.57 %. The established method has stable re－ coveries， high sensitivity， specificity， low interference and time-saving， which can be meet the determination requirements of mass aquatic products.
