摘　　要：目的测定中药常通口服液中重金属砷的含量。方法电感偶合等离子质谱法。结果与结论重金属砷在5￣25ng/ml浓度范围内线性关系良好(r=0.9998),平均回收率为98.94%(n=5,RSD=2.58%)。常通口服液中重金属砷含量符合规定。Objective To determine arsenic content in Changtong oral liquid, inductively coupled plasma-mass spectrometry （ICP-MS） was employed, which generated linear calibration curves in the range of 5-25 ng/ml for As （r=0.9998）. The average recovery of As was 98.94% （n=5, RSD=2.58%）.
