Antimony is known to have some adverse health effects on human health. Flame atomic absorption spectrometry (FAAS) is a widely used instrumental for the determination of antimony and other metals. However, it lacks the sensitivity to determine these metals at trace levels. This study was aimed at overcoming this setback by using hydrogen assisted T-shaped slotted quartz tube technique to preconcentrate and determine antimony by FAAS. All the system parameters were optimized to enhance the detection power of the system. Under the optimum experimental conditions, the limits of detection and quantification were found to be 0.75 and 2.49 µg L, respectively with R value of 0.9999. Accuracy of the developed method was validated by experimental results agreeing to the certified value of a standard reference material. Recovery studies were also carried out to determine the method's applicability to tap and mineral water samples, and the results obtained were appreciable.
已知锑会对人体健康产生一些不良影响。火焰原子吸收光谱法（FAAS）是一种广泛用于测定锑和其他金属的仪器。然而，它缺乏在痕量水平下测定这些金属的灵敏度。本研究旨在通过使用氢辅助T形开槽石英管技术对锑进行预富集并通过FAAS进行测定来克服这一挫折。对所有系统参数进行了优化，以提高系统的检测能力。在最佳实验条件下，检测限和定量限分别为0.75和2.49 μg/L，R值为0.9999。通过实验结果与标准参考物质的认证值相符，验证了所开发方法的准确性。还进行了回收率研究，以确定该方法对自来水和矿泉水样品的适用性，所得结果令人满意。
