ABSTRACT

Bacteria often floated in mid air, was inhaled in vivo, and could cause diseases. And adsorption properties of bamboo charcoal was not strong. Therefore, in order to enhanced adsorption and antibacterial effect, bamboo charcoal were pretreated by two silt and were analyzed by FT-IR. The results showed that VS’s and IS’s adsorption capacity were different for 0.5h, 1h, 1.5h, 2h, 2.5h, 3h, 3.5h, 4h, 4.5h, 5h, respectively. The optimal blast time were 2.5hof VS, and 0.5h of IS. Bamboo charcoal had the five characteristic absorption band during adsorption of VS and IS. S-S stretch, H2O stretch, O H stretch, C=O or C=C stretch, N–O or C=C stretch were observed at 3850 cm 1, 3730 cm 1, 3430 cm 1, 1660 cm 1, 1520cm 1, respectively. The transmissivity of IS’s peaks at 3850 cm 1, 3730 cm 1, 1660 cm 1, and 1520cm 1 achieved the maximum for 3.0h, and the transmissivity of the peaks at 3430cm 1 achieved the maximum for 1.0h. and the transmissivity of the VS’s peaks at 3850 cm 1, 3730 cm 1, 1660 cm 1, and 1520cm 1 achieved the maximum for 1.0h, and the transmissivity of the peaks at 3430cm 1 achieved the maximum for 4.5h. It provided the theory to enhance antibacterial activity od bamboo charcoal against bacteria transmit.
