The paper presents a novel method for simultaneous online examination of inorganic forms of aluminium: AlF(2)(+), AlF(2+,) and Al(3+) by means of the high performance liquid chromatography hyphenated with a detection by the atomic absorption spectrometry with flame atomization (HPLC-FAAS) without post-column reaction. The application of optimization procedure conditions of chromatographic separation of inorganic forms of aluminium was achieved by the analytical column IonPac CS5A (Dionex) with guard column IonPac CG5A (Dionex) and an aqueous ammonium chloride mobile phase, at pH about 3 with gradient elution. The separation of Al forms with nominal charge of 1+, 2+, 3+ required a run time of less than 8 min during a single analysis. The proposed method has been successfully used for the examination of aluminium forms formation AlF(n)((3-n)+) in environmental samples.
本文提出了一种通过高效液相色谱与火焰原子化原子吸收光谱检测联用（HPLC-FAAS）且无需柱后反应，同时在线检测铝的无机形态：AlF₂⁺、AlF₂⁺和Al³⁺的新方法。采用Dionex公司的IonPac CS5A分析柱和IonPac CG5A保护柱以及pH约为3的氯化铵水溶液流动相并进行梯度洗脱，实现了铝无机形态色谱分离优化程序条件的应用。单次分析中，对名义电荷为1⁺、2⁺、3⁺的铝形态进行分离所需运行时间不到8分钟。所提出的方法已成功用于检测环境样品中铝形态AlFₙ⁽³⁻ⁿ⁾⁺的形成。
