| Abstract: | The graphite tube such as Lanthanum-coated or Barium-coated have been tested for the determination of Be in water by GFAAS. The effects of different metal ions have been eliminated by adding Al (III) or Ca (III) as matrix modifier. The method is handy and fast. The recovery is 92.6%-105.0% and RSD is less than 10.24%. |
