Sulfur powder and sulfur dioxide (SO) often floated in air, produced acid rain and algal blooms, and could cause diseases. Bamboo charcoal could have adsorption and filtration properties. In order to figure out the optimal adsorption condition and the intrinsic change of the bamboo charcoal, five chemicals were adsorbed by bamboo charcoal and were analyzed by FT-IR. Fe(SO)'s, NaSO's, NaSO's, S's, and NaSO's optimal adsorption condition was the concentration of 19 g/1000 g and stir time of 20 min, 21 g/1000 g and stir time of 60 min, 7 g/1000 g and stir time of 120 min, 11 g/1000 g and stir time of 120 min, 21 g/1000 g and stir time of 60 min, respectively. FT-IR spectra showed that for FT-IR spectra of Fe(SO), the transmissivity of the peaks at 3435 cm and 2925 cm achieved the maximum for 60 min and the concentration was 19 g/1000 g, the transmissivity of the peaks at 1630 cm, 1060 cm and 660 cm achieved the maximum for 60 min and the concentration was 7 g/1000 g. For FT-IR spectra of NaSO, the transmissivity of the peaks at 1630 cm, 1060 cm and 660 cm achieved the maximum for 20 min and the concentration was 13 g/1000 g. For FT-IR spectra of NaSO, the transmissivity of the peaks at 3435 cm, 2925 cm, 1630 cm and 1060 cm achieved the maximum for 120 min and the concentration was 19 g/1000 g. For FT-IR spectra of S, the transmissivity of the peaks at 3435 cm, 2925 cm, 1630 cm and 1060 cm achieved the maximum for 20 min and the concentration was 11 g/1000 g, 17 g/1000 g and 21 g/1000 g. For FT-IR spectra of NaSO, the transmissivity of the peaks at 3435 cm achieved the maximum for 120 min and the concentration was 5 g/1000 g, the transmissivity of the peaks at 2925 cm, 1630 cm and 1060 cm achieved the maximum for 120 min and the concentration was 11 g/1000 g. In these states, the number of the transmissivity of the maximum peaks is the largest.
硫磺粉末和二氧化硫（SO）常常飘浮在空气中，形成酸雨和藻华，并可能引发疾病。竹炭具有吸附和过滤特性。为了找出竹炭的最佳吸附条件以及其内在变化，竹炭对五种化学物质进行了吸附，并通过傅里叶变换红外光谱（FT-IR）进行分析。硫酸铁（Fe(SO)₄）、亚硫酸钠（Na₂SO₃）、硫酸钠（Na₂SO₄）、硫（S）和亚硫酸氢钠（NaHSO₃）的最佳吸附条件分别为浓度19 g/1000 g且搅拌时间20分钟、21 g/1000 g且搅拌时间60分钟、7 g/1000 g且搅拌时间120分钟、11 g/1000 g且搅拌时间120分钟、21 g/1000 g且搅拌时间60分钟。傅里叶变换红外光谱显示，对于硫酸铁的傅里叶变换红外光谱，3435 cm⁻¹和2925 cm⁻¹处峰的透过率在60分钟且浓度为19 g/1000 g时达到最大值，1630 cm⁻¹、1060 cm⁻¹和660 cm⁻¹处峰的透过率在60分钟且浓度为7 g/1000 g时达到最大值。对于亚硫酸钠的傅里叶变换红外光谱，1630 cm⁻¹、1060 cm⁻¹和660 cm⁻¹处峰的透过率在20分钟且浓度为13 g/1000 g时达到最大值。对于硫酸钠的傅里叶变换红外光谱，3435 cm⁻¹、2925 cm⁻¹、1630 cm⁻¹和1060 cm⁻¹处峰的透过率在120分钟且浓度为19 g/1000 g时达到最大值。对于硫的傅里叶变换红外光谱，3435 cm⁻¹、2925 cm⁻¹、1630 cm⁻¹和1060 cm⁻¹处峰的透过率在20分钟且浓度为11 g/1000 g、17 g/1000 g和21 g/1000 g时达到最大值。对于亚硫酸氢钠的傅里叶变换红外光谱，3435 cm⁻¹处峰的透过率在120分钟且浓度为5 g/1000 g时达到最大值，2925 cm⁻¹、1630 cm⁻¹和1060 cm⁻¹处峰的透过率在120分钟且浓度为11 g/1000 g时达到最大值。在这些状态下，最大峰透过率的数量是最多的。
