Determination of Heavy Metals in Sulphur Fumigated and Drying from Different Areas by AAS
Objective: To investigate the content of heavy metals in Sulphur fumigated and Drying Lonicera japonica Thunb. Method: The sample is prepared via microwave digestion
the processing using the method of sulphur fumigated and drying
using atomic absorption spectroscopy to determine the content of Pb
Cd
As
Hg
Cu in sulphur fumigated and drying L. japonica. Result: The content of heavy metal in 10 batches of sulphur fumigated and drying Lonicera japonica.from different areas ware determined. The recovery rate was between 96.65% and 98.97%. Conclusion: The content of Pb
Cd
As
Hg and Cu in all samples were within the limitation
the content of Pb in the sample to be low after sulphur fumigated
