Abstract:

Arsenic present in Traditional Chinese Medicine (TCM) such as uncoated tablets, sugar coated tablet,black pills, capsules/powder, syrup, etc. was determined by using microwave digestion followed by Flow Injection Analysis (FIA) Inductively Coupled Plasma/Mass Spectrometry (ICP/MS). The effect of chloride in the determination of arsenic using FIA ICP/MS was investigated and was found that low level of chloride present do not enhance the 75As signal significantly.
