Sulfur and ammonia nitrogen are rich nutrient pollutants, after entering water can cause algal blooms, cause eutrophication of water body, the spread of them will not only pollute the environment, destroy the ecological balance, but also harm human health through food chain channels, especially drinking-water toxicosis. Acticarbon can adsorb harmful substances, it was beneficial for people's health. In order to figure out the optimal adsorption condition and the intrinsic change of acticarbon, five chemicals were adsorbed by acticarbon and analyzed by FT-IR. The optimal adsorption condition of Fe(SO), NaSO, NaSO, S and NaSO was 9 g/1000 g at 80 min, 21 g/1000 g at 20 min, 15g/1000 g at 20 min, 21 g/1000 g at 60 min and 21 g/1000 g at 100 min, respectively. FT-IR spectra showed that acticarbon had eight characteristic peaks, such as S-S stretch, HO stretch, O-H stretch, -C-H stretch, C[bond, double bond]O or C[bond, double bond]C stretch, CH bend, C-H were at 3850 cm, 3740 cm, 3435 cm, 2925 cm, 1630 cm, 1390 cm, 1115 cm, 600 cm, respectively. For FT-IR spectra of Fe(SO), the peaks at 3850 cm, 3740 cm, 2925 cm achieved the maximum with 9 g/1000 g at 20 min. For NaSO, the peaks at 2925 cm, 1630 cm, 1390 cm, 1115 cm, 600 cm achieved the maximum with 21 g/1000 g at 120 min. For ones of NaSO, the peaks at 3850 cm, 3740 cm, 1390 cm, 1115 cm, 600 cm, achieved the maximum with 2 g/1000 g at 80 min. For ones of S, the peaks at 3850 cm, 3740 cm, 2925 cm achieved the maximum with 19 g/1000 g at 100 min, the peaks at 1390 cm, 1115 cm, 600 cm achieved the maximum with 19 g/1000 g at 20 min. For FT-IR spectra of NaSO, the peaks at 1630 cm, 1390 cm, 1115 cm, 600 cm achieved the maximum with 2 g/1000 g at 100 min. It provided that acticarbon could adsorb and desulphurize from sulfur solution against drinking-water toxicosis.
硫和氨氮是富含营养的污染物，进入水体后可导致藻类大量繁殖，造成水体富营养化，它们的扩散不仅会污染环境、破坏生态平衡，还会通过食物链渠道危害人体健康，尤其是饮用水中毒。活性炭能吸附有害物质，对人体健康有益。为了找出活性炭的最佳吸附条件及内在变化，用活性炭吸附五种化学物质并通过傅里叶变换红外光谱（FT-IR）进行分析。Fe(SO)、NaSO、NaSO、S和NaSO的最佳吸附条件分别为：80分钟时9 g/1000 g、20分钟时21 g/1000 g、20分钟时15 g/1000 g、60分钟时21 g/1000 g和100分钟时21 g/1000 g。傅里叶变换红外光谱显示，活性炭有八个特征峰，如S-S伸缩振动、HO伸缩振动、O-H伸缩振动、-C-H伸缩振动、C[键，双键]O或C[键，双键]C伸缩振动、CH弯曲振动、C-H分别位于3850 cm、3740 cm、3435 cm、2925 cm、1630 cm、1390 cm、1115 cm、600 cm处。对于Fe(SO)的傅里叶变换红外光谱，3850 cm、3740 cm、2925 cm处的峰在20分钟时9 g/1000 g达到最大值。对于NaSO，2925 cm、1630 cm、1390 cm、1115 cm、600 cm处的峰在120分钟时21 g/1000 g达到最大值。对于NaSO的光谱，3850 cm、3740 cm、1390 cm、1115 cm、600 cm处的峰在80分钟时2 g/1000 g达到最大值。对于S的光谱，3850 cm、3740 cm、2925 cm处的峰在100分钟时19 g/1000 g达到最大值，1390 cm、1115 cm、600 cm处的峰在20分钟时19 g/1000 g达到最大值。对于NaSO 的傅里叶变换红外光谱，1630 cm、1390 cm、1115 cm、600 cm处的峰在100分钟时2 g/1000 g达到最大值。这表明活性炭可以从硫溶液中吸附并脱硫以防止饮用水中毒。
