| Abstract: | Using of 6mol ?L-1 hydrochloric acid and 0.1% KBH1 .Provides an ideal way to eliminate the interference of 8mg ?rnl-1 of Ni in the determination of Te hy hydride generation. Te as hydride is thus pre-concent rated in a graphite tube coated with Pd.A method for the direct determinatin of Te in nickel base alloy is established with satisfactory results. |
