Abstract:
The Atomic Absorption Spectrophotometry method for quantifying the lead and copper content of some herb products containing Panax pseudoginseng was reported. The proposed process of analyzing, using Graphite Furnace Atomizing Mode, were applied for 5 randomly selected samples and proved to be accurate. Results: Lead calibration curve: standard solution have exact lead concentrations of 10, 20 and 30ng/ml in 2% nitric acid. Copper calibration curve: standard solutions have exact copper concentration of 5, 10 and 20ng/ml in 2% nitric acid. Both techniques for decomposition of samples, wet ashing and microwave can be used in preparation of sample solutions
