本研究探討陽極氧化鋁(Anodic Aluminum Oxide, AAO)對於分離方面的研究，在本研究中將分為兩個部分，其一是將阻障層利用蝕刻進行通孔處理，把AAO作為篩網，利用孔徑大小的不同，來分離不同粒徑大小之顆粒，其二是利用薄膜的技術概念，讓AAO作為薄膜，使混合溶液透過未通孔的阻障層，實行擴散作用，利用薄膜兩側壓力差，並進行分離。
首先進行混合溶液之分離實驗，調配異丙醇與水的比例為7：3作為模擬工業廢水，透過氣相層析儀(Gas chromatography,GC)進行濃度檢測後，將AAO作為分離薄膜，另外研究不同製備參數使阻障層厚度產生變化，浸泡磷酸進行阻障層蝕刻與實施降電壓處理(Barrier layer thinning,BLT)，都能使阻障層變薄，讓擴散時間縮短，預期透過阻障層變薄而增加通量，在進行滲透汽化(Pervaporation)實驗，須蒐集容器浸泡至液態氮中，由於分離出來的溶液是呈現氣體狀，因此利用液態氮強制凝結，將分離出來的溶液進行GC檢測濃度，將蒐集容器比較前後重量差異，即可得出薄膜分離的兩大重要數據通量與選擇性。
陽極氧化鋁(Anodic Aluminum Oxide, AAO)作為過濾薄膜(Filter membrane)的應用，利用不同電解液所製備出AAO，其中含有草酸與磷酸作為電解液，並實行通孔處理，孔洞可以調整100至450nm之間，利用孔洞與顆粒大小差異，來達到快速分離的目的。首先要使用SEM觀測溶液中銀奈米顆粒的粒徑大小，並進行EDS成分分析，才能選擇使用適當的陽極參數來製備過濾膜，分離完的溶液，使用粒徑分析儀來分析溶液過濾前後粒徑大小分布，並使用紫外光 -可見光譜儀 (UV- Visible Spectrometry)分析 ，來討論銀奈米顆粒分離後，銀奈米線對於光吸收度的效果。

In this study, we investigate the separation of Anodic Aluminum Oxide (AAO), which is divided into two parts. First, the barrier layer is etched with through-hole process, and AAO is used as a filter to separate particles of different sizes by using the difference of pore size. The second is to make use of the film technology concept, so that the mixed solution can be diffused through the barrier layer without through-hole, and the pressure difference between the two sides of the film can be used to separate the particles.
Firstly, the separation experiment of the mixed solution was carried out by mixing isopropyl alcohol to water in the ratio of 7:3 to simulate industrial wastewater, and the concentration of AAO was measured by gas chromatography (GC), and then the separation film was used. In addition, the barrier layer thickness was changed by different preparation parameters, and the barrier layer etching by dipping in phosphoric acid and the barrier layer thinning (BLT) treatment could make the barrier layer thinner and shorten the diffusion time. Since the separated solution is in the form of a gas, liquid nitrogen is used to force condensation, and the separated solution is tested for concentration by GC, and the two important data of flux and selectivity of thin film separation can be obtained by comparing the weight difference between the collected containers.
Anodic Aluminum Oxide (AAO) is used as a filter membrane. AAO is prepared by using different electrolytic solutions, which contain oxalic acid and phosphoric acid as the electrolyte, and through-hole treatment is performed. to achieve the purpose of rapid separation. Firstly, the size of silver nanoparticles in the solution should be observed by SEM and analyzed by EDS composition before selecting the appropriate anode parameters for the preparation of the filter membrane. The effect of silver nanoparticles on light absorption after separation of silver nanoparticles was discussed by UV-visible spectrometry.
