Abstract
Different kinds of graphite tubes - uncoated, pyrolytically coated, tungsten and zirconium coated - have been tested for optimisation of operating conditions for determination of chromium by GFAAS method. The effect of mineral acids and many metal ions on the absorption signal of chromium has been investigated. The best results were obtained for pyrolytically coated tubep.Keywords
