| Abstract: | The optimum Experimental condition for the determination of Cr was selected. The interferences of different acids and matrices werestudied. Ammonia water as matrix modifier can be used to decrease calculated and experimental characteristic masses was studied. The possibility of using pyrolytic coated graphite tube for standardless analysis of environmental chromium has been discussed. |
