活性炭孔隙结构对活性炭过滤纸吸附性能的影响
Effect of Pore Structure of Activated Carbon on Performance of Activated Carbon Filter Paper
摘要
Abstract
The pore structures of four different types of activated carbons, which included two wood-based activated carbons AC1, AC2, one coal-based activated carbon AC3 and one coconut-shell-based activated carbon AC4, were characterized by nitrogen adsorption method and scanning electron microscope. The activated carbon filter papers were prepared by papermaking process. The adsorption performances of the filter papers were characterized by adsorption values of methylene blue and phenol. The effect of pore structure characteristics of activated carbon on performance of activated carbon filter papers was studied. The results showed that: Among the four types of activated carbons, two types of wood-based activated carbons have larger specific surface areas and higher total pore volume, which are 1054 mVg, 1.165 cm Vg and 1125 mVg, 1.083 cm Vg respectively. Though the micropores mean diameters of the four activated carbons are similar, the mesopores and macropores mean diameters of the two wood-based activated carbons AC1 and AC2 are larger. In pore structure of wood-based activated carbon AC2, the micropores, mesopores and macropores volumes ore higher than those of other samples. And the pores with diameters of a-bout 0.64 hid , 1.2 nm and 2.3 nm are abundant. The selective adsorption of activated carbon AC2 is strong. So the filler papers made of activated carbon AC2 are the most effective in adsorption of methylene blue and phenol, and after filtration for three times the adsorption rates for melhylene blue and phenol are 92. 4% and 93. 8% respectively.关键词
