水中有機酸常是淨水場中形成消毒副產物之反應物，因此本研究利用動力及平衡吸附實驗探討商用奈米碳管對水中有機酸之吸附特性及模式解析，吸附試驗之主要影響因子包括有機酸濃度（以黃酸為例）、pH 值、離子強度及溫度。實驗結果顯示，動力吸附試驗約在120 min可達到平衡，吸附量隨著黃酸濃度增加及離子強度減少而增加，動力實驗結果以Modified Freundlich equation、Pseudo-1st-order equation、Pseudo-2nd-order equation三模式套用，結果以Modified Freundlich equation模擬最佳；由Intraparticle Diffusion equation模式解析，顯示吸附過程由孔隙擴散所掌控。等溫吸附試驗在恆溫4 – 45oC範圍內，最大吸附量為26.094 – 20.772 mg/g，試驗數據皆可適用Langmuir及Freundlich模式。熱力學參數ΔGo值為-0.930 – -1.014 kcal/mol、△Ho為-1.561 kcal/mol，△So為-2.02 cal/mol，顯示吸附過程屬於自發性放熱反應。在高黃酸濃度、低離子強度、低pH值及低溫狀態等條件下，為有利於奈米碳管對黃酸之吸附。

Organic acids are usually the reactants which proceed in chlorination reaction into products of disinfection by-products in water treatment plant. The purpose of this study is by using tests of kinetics and equilibrium adsorptions to investigate adsorption characteristics and kinetic model evaluations of selected organic acid in solution. We use commercial carbon nano-tube for the adsorbents. The major factors in adsorption tests include the concentration of fulvic acid (a typical organic acid in raw water), pH, ionic strength and temperature. Experiment results exhibited kinetic adsorption reached equilibrium about 120 minutes, the adsorption capacity increased with concentrations increasing of fulvic acid and decreased with ionic strengths. The best selection in kinetic models evaluation, fitting models such as Modified Freundlich equation, Pseudo-1st-order equation and Pesudo-2nd-oder equation is Modified Freundlch equation model. In addition, intraparticle diffusion equation model was fitted well and showed adsorption process was controlled with pore diffusion. The maximum adsorption capacity varied from 26.094 to 20.772 mg/g when temperature ranging from 4 to 45℃. Isotherm adsorption results were fitted on Langmuir and Freundich models. The ΔG° values ranged from -0.930 to -1.014 kcal/mol, ΔH°:-1.561 kcal/mol and ΔS°:-2.02 cal/mol. Thermodynamic parameters indicated that the adsorption is spontaneously and an exothermic reaction. Adsorption of fulvic acid by carbon nano-tube has a good performance when operation conditions of higher fulvic acid concentration, lower ionic strength, lower pH and lower temperature.
