模糊正交法用于石墨炉探针原子化测定铋条件的研究

模糊正交法是通过把正交试验结果模糊化,然后用模糊数学的理论和方法来处理实验数据。与常规正交设计相比,能在同样实验工作量的情况下获得更多的信息。本文采用模糊正交法对元素Bi的测定条件进行优化,并将其同常规正交设计方差分析的结果进行了比较,并提出一个综合评价参数,对建立的分析方法进行了综合评价。

Determination Bismuth With the Probe Atomization in Graphite Furnace Atomic Absorption Spectrometry Using Fuzzy Orthogonal Design

A new comprehensive evaluation index was proposed. According to the evaluation index proposed , the determination condition of Bi was optimized using fuzzy orthogonal design. The results declared that fuzzy analysis might estimate not only main effect of factors, but also possible optimal combination among factors. This is the superiority of fuzzy orthogonal design over conventional orthogonal design. The trace amount of Bi in kaolin was determined using graphite furnace atomic absorption spectrometry with the graphite probe atomization with satisfactory results.
