Abstract A comparative study of Sb(III) exposition is presented. The determination of trace amounts of Sb(III) present in tobacco samples (tobacco of conventional cigarettes, refill solutions for e-cigarettes, snuff used in water pipe, snus and dry rape) has been realized by solid surface fluorescence using alizarin as fluorogenic reagent (λem = 450 nm, λexc = 363 nm). In a first step, a chemisorption on filter paper was carried out with the bile salt sodium cholate (pH 10.2). In these conditions, the metal was selectively retained on the solid support preventing the spectral interferences of the complex matrix. The calibration graphs resulted linear in the range of 0.24 to 304.4 μg L−1 with detection limit of 0.08 μg L−1 (S/N = 3.3). Results were truenessed by ETAAS with adequate agreement. The results will be used in prevention workshops for the purpose to provide scientific evidence to serve young people to make a correct decision respect the tobacco consumption.

卷烟和烟草消费替代品中锑暴露的比较研究

摘要 介绍了 Sb(III) 暴露的比较研究。使用茜素作为荧光试剂,通过固体表面荧光测定烟草样品(传统卷烟的烟草、电子烟的补充液、水管中使用的鼻烟、鼻烟和干油菜)中存在的痕量 Sb(III) (λem = 450 nm,λexc = 363 nm)。在第一步中,用胆酸钠(pH 10.2)在滤纸上进行化学吸附。在这些条件下,金属被选择性地保留在固体载体上,防止了复杂基质的光谱干扰。校准图在 0.24 至 304.4 μg L-1 的范围内呈线性,检测限为 0.08 μg L-1 (S/N = 3.3)。结果由 ETAAS 验证,并具有足够的一致性。
