Sulfur particles, which could cause diseases, were the main powder of smog. And activated carbon had the very adsorption characteristics. Therefore, five sulfur particles were adsorbed by activated carbon and were analyzed by FT-IR. The optimal adsorption time were 120 min of NaSO, 120 min of NaSO, 120 min of NaSO, 120 min of Fe(SO) and 120 min of S. FT-IR spectra showed that activated carbon had the eight characteristic absorption of S-S stretch, HO stretch, O-H stretch, -C-H stretch, conjugated C[bond, double bond]O stretch or C[bond, double bond]C stretch, CH bend, C-O stretch and acetylenic C-H bend vibrations at 3850 cm, 3740 cm, 3430 cm, 2920 cm, 1630 cm, 1390 cm, 1110 cm and 600 cm, respectively. For NaSO, the peaks at 2920 cm, 1630 cm, 1390 cm and 1110 cm achieved the maximum at 20 min. For NaSO, the peaks at 3850 cm, 3740 cm and 2920 cm achieved the maximum at 60 min. The peaks at 1390 cm, 1110 cm and 600 cm achieved the maximum at 40 min. For NaSO, the peaks at 3430 cm, 2920 cm, 1630 cm, 1390 cm, 1110 cm and 600 cm achieved the maximum at 60 min. For Fe(SO), the peaks at 1390 cm, 1110 cm and 600 cm achieved the maximum at 20 min. For S, the peaks at 1630 cm, 1390 cm and 600 cm achieved the maximum at 120 min. It provided that activated carbon could remove sulfur particles from smog air to restrain many anaphylactic diseases.
可引发疾病的硫颗粒是雾霾的主要成分。而活性炭具有很强的吸附特性。因此，用活性炭吸附了五种硫颗粒，并通过傅里叶变换红外光谱（FT-IR）进行分析。最佳吸附时间分别为：亚硫酸钠120分钟、亚硫酸氢钠120分钟、亚硫酸120分钟、硫酸铁120分钟、单质硫120分钟。傅里叶变换红外光谱显示，活性炭在3850厘米-1、3740厘米-1、3430厘米-1、2920厘米-1、1630厘米-1、1390厘米-1、1110厘米-1和600厘米-1处分别有硫-硫伸缩、羟基伸缩、氧-氢伸缩、碳-氢伸缩、共轭羰基伸缩或碳-碳双键伸缩、碳氢键弯曲、碳-氧伸缩和炔碳-氢键弯曲振动的八个特征吸收峰。对于亚硫酸钠，在2920厘米-1、1630厘米-1、1390厘米-1和1110厘米-1处的峰在20分钟时达到最大值。对于亚硫酸氢钠，在3850厘米-1、3740厘米-1和2920厘米-1处的峰在60分钟时达到最大值。在1390厘米-1、1110厘米-1和600厘米-1处的峰在40分钟时达到最大值。对于亚硫酸，在3430厘米-1、2920厘米-1、1630厘米-1、1390厘米-1、1110厘米-1和600厘米-1处的峰在60分钟时达到最大值。对于硫酸铁，在1390厘米-1、1110厘米-1和600厘米-1处的峰在20分钟时达到最大值。对于单质硫，在1630厘米-1、1390厘米-1和600厘米-1处的峰在120分钟时达到最大值。这表明活性炭可以去除雾霾空气中的硫颗粒，从而抑制多种过敏性疾病。
