開發奈米級聚苯胺複合材料應用於水體抑菌作用之研究

根據資料指出，台灣水產養殖業淡水用水量每年平均為 6,800 萬噸，顯示養殖水產業需要之大量淡水。而由於台灣地形因素導致水資源長期匱乏，淡水資源取得並不容易，因此如何將水資源重覆運用已變成一重要課題。對台灣而言，高密度養殖漁業對水的潔淨度有很高的要求，大多數的養殖場都具有十分良好的水處理回收系統，但其設備系統造價極為昂貴，加上因此研發便宜的處理設備是近年的熱門研究項目。聚苯胺結構特性之多樣涵蓋物理、化學、磁性、電性等多種方面應用價值，近年更有許多研究報告指出聚苯胺能有效抑制細菌、黴菌及真菌。而本實驗利用十二烷基苯磺酸及二氧化鈦摻雜聚苯胺，主要探討應用於用水系統之抗菌效果，研究包括對聚苯胺複合材料及複合濾材之特徵鑑定，並將複合式材料及濾材應用於瓶杯抗菌實驗及實際水樣抗菌中，記錄結果並分析數據。結果顯示，在水體中粉體的抗菌實驗中，聚苯胺粉末5g/L 與大腸桿菌(濃度：106 CFU/L)接觸30分鐘後，即可達到抗菌率100%之效果，相同條件下金黃色葡萄球菌之抗菌率為80%。聚苯胺複合濾材在瓶杯抗菌試驗中，大腸桿菌及金黃色葡萄球菌皆於30分鐘內達到抗菌率99.99%以上。濾材實體水樣抗菌實驗中，汙水廠放流水(原水生菌數: 2*106 CFU/L ) 接觸30分鐘後，抗菌率便達到100%，養殖場水樣(原水生菌數: 8.5*107 CFU/L ) ，於反應一天之後達成抗菌率100%，證明複合式濾材在實體水樣具有潛力的抗菌能力。

According to the data, the average annual freshwater water consumption in Taiwan's aquaculture industry is 68 million tons per year, indicating that the aquaculture industry needs a large amount of fresh water. It is not easy to obtain fresh water resources because of the long shortage of water resources caused by terrain factors in Taiwan. Therefore, how to reuse water resources has become an important subject. For Taiwan, high-density aquaculture fisheries have a high degree of cleanliness requirements for water, and most farms have a very good water treatment and recovery system, but their equipment systems are extremely costly and therefore inexpensive Equipment is a popular research project in recent years. Polyaniline structural characteristics cover a wide range of physical, chemical, magnetic, electrical and other aspects of application value, in recent years, many studies have pointed out that polyaniline can effectively inhibit bacteria, mold and fungi. In this study, dodecyl benzene sulfonic acid and titanium dioxide doped polyaniline were used to study the antibacterial effect of water system. The research included the identification of polyaniline composite material and composite filter, and composite materials and filter materials used in the bottle of antibacterial experiments and the actual water sample antibacterial, record the results and analyze the data. The results showed that the antimicrobial effect of polyaniline powder 5g / L in Escherichia coli (concentration: 106 CFU / L) was 30%, and the antibacterial rate was 100%. Under the same conditions, the antibacterial rate of Staphylococcus aureus was 80%. Polyaniline composite filter in the bottle cup antibacterial test, E. coli and Staphylococcus aureus in 30 minutes to reach the antibacterial rate of 99.99% or more. In the antibacterial experiment of the filter material, the antibacterial rate was 100% after the contact with the effluent (2 * 106 CFU / L) of the sewage plant (the number of raw bacteria: 8.5 * 107 CFU / L), reached an antibacterial rate of 100% after one day of reaction, demonstrating that the composite filter has the potential for antibacterial activity in the solid water sample.
