摘要:	本研究主要針對嵌印高分子及離子交換樹脂在近等電點時的吸附機制進行探討，實驗上主要是利用恆溫滴定微卡計(Isothermal Titration Calorimetry，ITC)量測吸附熱及配合等溫吸附線的建立，期望從熱力學的角度來研究分析。在嵌印高分子及離子交換樹脂在近等電點時的吸附機制研究方面，我們分別提出了模板分子2,4-D與嵌印高分子及控制組高分子的可能鍵結程序，並說明各鍵結程序對於整個系統的焓△Hads與火商 △Sads 的影響及 The aim of the research is to provide the insight of the binding mechanism of imprinting polymer and ion-exchange resin near isoelectric point by isotherm curve analysis and adsorption enthalpy measurement by microcalorimetry. We suggested a possible binding processes of 2,4-dichlorophoxyacetic acid (2,4-D) adsorbing on imprinting and control polymers and divided the process into four subprocesses; (a) dehydration process of imprinting polymer; (b) dehydration process of 2,4-D; (c) binding process of 2,4-D adsorbing on imprinting polymer and (d) rearragement process of water molecules after 2,4-D adsorbing on imprinting polymer. The thermodynamic information accompany the suggested process were also discussed. The data measured using isothermal titration calorimetry (ITC) for both imprinting and control polymers reveals the values of adsorption enthalpy (
