本研究之目的係利用表面改質之混酯纖維素微孔濾膜吸附水中之重金屬離子。濾膜表面改質係利用鹼性水解、過碘酸根氧化與席夫置換三個系列化學反應，將濾膜表面結構官能基轉換成為能與重金屬離子產生錯合鍵結反應之肟基，以吸附水中之重金屬離子。表面改質反應產生之肟基量經化學定量分析，估計單位面積改質濾膜的肟基含量為7.9×10-7 mol/cm2。本研究利用平衡吸附與直流式過濾兩種方式測定改質濾膜對鎳、鉛、鋅與二價銅離子的吸附效果，並探討改質濾膜對這四種重金屬離子的吸附機制與反應動力學。

This study involved using a surface-functionalized mixed cellulose ester microfiltration membrane to remove heavy metal ions from water. The surface functionalization of the membrane was achieved through three sequential reactions: alkaline hydrolysis, periodate oxidation, and Schiff’s replacement. The membrane surface functional groups were chemically transformed into oxime groups capable of chelating heavy metal ions. The oxime groups of the membrane produced through the three reactions were chemically analyzed. The average amount of oxime groups was estimated to be 7.9 × 10-7 mol/cm2 of the membrane area. The sorption of heavy metal ions including nickel(II), lead(II), zinc(II) and cupric ions by the membranes was determined by performing equilibrium sorption and dead-end filtration. The mechanism and reaction kinetics of the sorption of these heavy metal ions by the membranes were also examined.
