应用正交设计研究火焰原子吸收分析中的干扰效应

Computational eliminating the interference effects of flame atomic absorption analysis by orthogonal design

摘要: 采用正交多项式回归设计方法, 试验和研究了稀土氧化物中钙的火焰原子吸收光谱法(FAAS)测定时的干扰效应。结果表明:该方法可以有效地研究和消除干扰效应。用回归方程修正的结果和实际浓度一致。

Abstract: The interference effects for FAAS determining calcium in RE oxides were studied by using orthogonal polynomial regression design.In this paper, it is shown that the method is efficient to study and eliminate interference effects in FAAS and the results corrected by using polynomial regressive equation are consistent with the actual concentrations.
