摘要
通过选择碲的氢化物发生条件,克服了高含量镍对碲的干扰。把氢化物富集在涂钯石墨管里,然后再原子化,成功地测定了高温镍基合金中碲。
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.
