Abstract This work was the expansion and in-depth study based on the previously established non-aqueous phase HG system. Aiming at the determination of antimony by the developed non-aqueous phase HG, the effect of different organic media and the sensitization effect of surfactant on the non-aqueous phase HG reaction were investigated. As an important condition, organic media has an important influence on this method. This study found that the surfactant Triton X-114 had very good sensitization effect for non-aqueous HG reaction. The sensitization effect of surfactant in different organic media was different. Among the investigated media, the comprehensive performance of octanol was the best under the sensitization effect of surfactant. Compared with the analytical performance of not adding surfactant, the sensitization factor of the surfactant was 1.55. The sensitization effect of surfactant Triton X-114 on the HG reaction in the octanol media was very significant, which greatly improved the analytical performance of the non-aqueous HG method. Under the optimal conditions, the limit of detection (LOD) was 0.04 μg/L. Compared to conventional HG-AFS, the efficiency of non-aqueous phase HG and the analytical performance of the developed method was considerably improved.

非水相氢化物发生-原子荧光光谱法测定锑中有机介质和表面活性剂敏化作用的研究

摘要 这项工作是在先前建立的非水相汞系统的基础上进行的扩展和深入研究。针对开发的非水相HG测定锑，研究了不同有机介质的影响和表面活性剂对非水相HG反应的敏化作用。作为一个重要条件，有机介质对这种方法有重要影响。本研究发现表面活性剂Triton X-114对非水HG反应有很好的敏化作用。表面活性剂在不同有机介质中的敏化作用不同。在所考察的介质中，辛醇在表面活性剂增敏作用下的综合性能最好。与不加表面活性剂的分析性能相比，表面活性剂的敏化因子为1.55。表面活性剂 Triton X-114 对辛醇介质中 HG 反应的敏化作用非常显着，大大提高了非水 HG 方法的分析性能。在最佳条件下，检测限（LOD）为0.04 μg/L。与传统的 HG-AFS 相比，非水相 HG 的效率和所开发方法的分析性能得到了显着提高。
