中文摘要:
      通过对测定条件的优化,采用高钒系列标准样品建立分析程序,完成类型标准化,校验后再进行测定,建立了火花直读光谱法对铝及铝合金中的钒含量进行测定的方法。选用E2235高钒标准样品进行标准化,所得测定值与标准值基本一致,相对标准偏差为2.9%(n=8)。结果表明,当测定元素含量不超过0.020%时,方法准确、可靠,适合于铝及铝合金中微量钒含量的测定。
英文摘要:
      A method was developed for the determination of vanadium (V) in aluminum samples at optimized test conditions. A program was established for standardization and was used after verification. The analytical results agreed with the standard value for the high vanadium standard sample of E2235. The relative standard deviation of this method using spark emission spectrometry was 2.9 % (n=8). The results show that the method is accurate for analyte concentration less than 0.020 %. The proposed method is reliable and suitable for determining trace amounts of V in aluminum and aluminum alloys.
