| 摘 要： | 对椰壳活性炭、煤质活性炭、木质活性炭进行了腐殖酸吸附性能的研究,通过对比不同活性炭材料对腐殖酸的吸附数据,评价不同材质活性炭吸附腐殖酸的性能,根据弗罗因德利希吸附等温式得出椰壳活性炭、煤质活性炭、木质活性炭吸附腐殖酸吸附容量k分别为0.872 8、0.842 8、0.517 3(mg/g)/(mg/L)1/n,吸附强度1/n分别为0.904 4、0.979和0.996 1。结果表明,椰壳活性炭的吸附容量大,更容易吸附。

| Abstract: | In this paper, coconut shell activated carbon, coal activated carbon, wood activated carbon in the humic acid adsorption performance were studied. Comparing different activated carbon materials for humic acid adsorption data, assess the effects of different material activated carbon adsorption degree humic acid. According to Freundlich adsorption isotherm, it was concluded that the coconut shell activated carbon, the coal activated carbon, the wood activated carbon and its adsorption capacity k was 0.8728 (mg.g-1)/(mg.L)1/n, 0.8428 (mg.g-1)/(mg.L)1/n, 0.5173 (mg.g-1)/(mg.L)1/n, respectively. 1/n and adsorption strength was 0.9044, 0.979, 0.9961, respectively. This results showed that the coconut shell activated carbon had the largest adsorption capacity, adsorption was the most easily. |
