中文摘要 | 本研究使用粒狀活性碳迷你管柱決定活性碳吸附水中Atrazine之吸附量。在進流水濃度為10μg/L之情況下,迷你管柱中Atrazine之吸附量(0.6-2.4mg/g)低於由等溫吸附線所決定之Atrazine平衡吸附容量。迷你管柱中Atrazine之吸附量隨著填充迷你管柱所使用粒狀活性碳粒徑之增加而降低。本研究所得結果可用以解釋在模廠內連續操作30週之粒狀活性碳吸附塔所量得之吸附量。 |
英文摘要 | This study uses granular activated carbon (GAC) minicolumns to determine the amount of atrazine adsorbed. With an influent concentration of 10μg/L, the amount of atrazine adsorbed on the minicolumns (0.6 to 2.4mg/g, depending upon the GAC particle size) was 8-77% less than the capacity calculated from the batch adsorption isotherms (2.6mg/g). It is observed that the amount of atrazine adsorbed decreases as the diameter of the GAC particle increases. The results obtained seem in reasonable agreement with concentrations of atrazine found at the top of a filter-adsorber and post-contactor previously operated for 30 weeks at Waterford Water Works, NY, where the amounts of atrazine adsorbed were measured as 0.7 and 0.5mg/g, respectively. |
