| Abstract: | A method of microwave digestion - graphite furnace atomic absorption spectrophotometry was established to determine the quantity of lead, cadmium, chromium, antimony, nickel and copper in cinnamon. Under the selected experimental conditions, the correlation coefficients of the standard curve for each element were above 0.99, the RSD was under 5%, and the recovery was between 97.75% and 100.95%. The results indicated that the method which was convenient, fast, accurate, and highly sensitive, can be used for the determination of lead, cad- mium, chromium, copper, nickel, antimony in cinnamon. |
