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。
In this paper, the humic acid adsorption performance of coconut shell activated carbon, coal activa-ted carbon and wood activated carbon were studied. The effects of different kinds of activated carbon on degree of humic acid adsorption were assessed by comparing humic acid adsorption data of different activated carbon, Accord-ing to Freundlich adsorption isotherm, it was concluded that the coconut shell activated carbon, the coal activated carbon and the wood activated carbon has an adsorption capacity k of 0. 872 8 ,0 . 842 8 and 0. 517 3 （m g /g ） / （mg/L）1/n respectively, adsorption strength 1/n being 0.904 4 , 0.979 and 0.996 1 respectively. The results showed that the coconut shell activated carbon had the largest adsorption capacity, and the adsorption happened the most easily.
