【Abstract】 The samples were dissolved by hydrochloric acid and nitric acid. Both of ammonium dihydrogen phosphate and magnesium nitrate as matrix improvers were added into testing solution. Copper and lead were determined by GFAAS. The detection limit was 0.68 μg/L for copper and 1.57 μg/L for lead.This method was simple,rapid and accurate.The results were satisfactory.更多还原
