Abstract

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 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 Fe2(SO4)3, the transmissivity of the peaks at 3435 cm-1 and 2925 cm-1 achieved the maximum for 60 min and the concentration was 19 g/1000 g, the transmissivity of the peaks at 1630 cm-1, 1060 cm-1 and 660 cm-1 achieved the maximum for 60 min and the concentration was 7 g/1000 g. For FT-IR spectra of Na2SO4, the transmissivity of the peaks at 1630 cm-1, 1060 cm-1 and 660 cm-1 achieved the maximum for 20 min and the concentration was 13 g/1000 g. For FT-IR spectra of Na2S2O8, the transmissivity of the peaks at 3435 cm-1, 2925 cm-1, 1630 cm-1 and 1060 cm-1 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-1, 2925 cm-1, 1630 cm-1 and 1060 cm-1 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 Na2SO3, the transmissivity of the peaks at 3435 cm-1 achieved the maximum for 120 min and the concentration was 5 g/1000 g, the transmissivity of the peaks at 2925 cm-1, 1630 cm-1 and 1060 cm-1 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.
