摘要 磷元素在适宜的空气-乙炔火焰中可形成PO双原子分子,PO分子的部分吸收谱线具有原子谱线的轮廓和强度。该文主要研究了利用连续光源原子吸收光谱法,在空气-乙炔火焰条件下测定PO分子的吸光度值,从而测定土壤样品中的磷元素。实验研究了测定过程中可能存在的光谱干扰和化学干扰、乙炔/空气流速比、燃烧器高度对PO双原子分子吸光度的影响,以及不同消解方式对测定结果的影响。在优化的实验条件下,PO246.40nm的检出限为20mg/L。通过对土壤标准物质中磷元素含量的测定比对证明,连续光源原子吸收光谱法是一种测定土壤中磷元素含量的简单、快速的方法。 A method was developed for the determination of phosphorus(P) using a high-resolution continuum source atomic absorption spectrometer. It is based on measuring the sharp molecular absorption bands of phosphorus monoxide(PO) formed in the air- acetylene flame. The effects of the experimental parameters including the disgestion modes, spectral and chemical interferences, the air - acetylene ratio and the burner height on the analytical results of P in soil were investigated. Under optimum conditions, the detection limit of P at the PO wavelength of 246.40 nm was 20 mg/L. The proposed method was evaluated by analyzing two soil reference materials. The results agreed quite well with the certified values.
