摘　　要：实验利用电感耦合等离子体质谱仪,对盐及盐化工产品中镉的测定方法进行了研究。文中对氯化钠基体的干扰程度进行了评价,选择利用内标法消除基体干扰,确立了适合的实验方法。方法检出限为0.003μg/L,精密度RSD≤0.47%,平均回收率95.8%。该方法结果准确,检出限低,非常适合盐及盐化工产品的镉含量的测定。It was carried out that the study of cadmium determination in salt product and salt chemical product by inductively coupled plasma mass spectrometry. The matrix interference of salt was analyzed. A new method of inductively coupled plasma mass spectrometry for the determination of cadmium in salt product and salt chemical product was studied. The detection limit was 0.003 μg/L. RSD was better than 0.47%,and the average recovery was 95.8%. This method is accurate,stable,low detecting limit and extremely suitable for the determination of cadmium in salt product and salt chemical product.
