Abstract:
Objective To determine the content of the heavy metal Cadmium(Cd)in Changtong oral liquid.Methods Inductively coupled plasma mass spectrometry(ICP -MS )was used.Results The calibration curve was linear in t he range of 0.0025～0.0125?g /mL for Cd(r=0.9997).The average recovery of the heavy me tal element of Cd was99.37%(n=5,RSD =2.73%).Conclusion This method is simple,accurate and e ffective.It can be used for the quality control of Changtong oral li quid.
