| 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. |
