Sulfur powder and sulfur dioxide (SO2) 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. Fe2(SO4)3's, Na2SO4's, Na2S2O8's, S's, and Na2SO3's optimal adsorption condition was the concentration of 19Â g/1000Â g and stir time of 20Â min, 21Â g/1000Â g and stir time of 60Â min, 7Â g/1000Â g and stir time of 120Â min, 11Â g/1000Â g and stir time of 120Â min, 21Â g/1000Â g and stir time of 60Â min, respectively. FT-IR spectra showed that for FT-IR spectra of Fe2(SO4)3, the transmissivity of the peaks at 3435Â cmâ1 and 2925Â cmâ1 achieved the maximum for 60Â min and the concentration was 19Â g/1000Â g, the transmissivity of the peaks at 1630Â cmâ1, 1060Â cmâ1 and 660Â cmâ1 achieved the maximum for 60Â min and the concentration was 7Â g/1000Â g. For FT-IR spectra of Na2SO4, the transmissivity of the peaks at 1630Â cmâ1, 1060Â cmâ1 and 660Â cmâ1 achieved the maximum for 20Â min and the concentration was 13Â g/1000Â g. For FT-IR spectra of Na2S2O8, the transmissivity of the peaks at 3435Â cmâ1, 2925Â cmâ1, 1630Â cmâ1 and 1060Â cmâ1 achieved the maximum for 120Â min and the concentration was 19Â g/1000Â g. For FT-IR spectra of S, the transmissivity of the peaks at 3435Â cmâ1, 2925Â cmâ1, 1630Â cmâ1 and 1060Â cmâ1 achieved the maximum for 20Â min and the concentration was 11Â g/1000Â g, 17Â g/1000Â g and 21Â g/1000Â g. For FT-IR spectra of Na2SO3, the transmissivity of the peaks at 3435Â cmâ1 achieved the maximum for 120Â min and the concentration was 5Â g/1000Â g, the transmissivity of the peaks at 2925Â cmâ1, 1630Â cmâ1 and 1060Â cmâ1 achieved the maximum for 120Â min and the concentration was 11Â g/1000Â g. In these states, the number of the transmissivity of the maximum peaks is the largest.
