本研究探討以回收保麗龍為材料,經靜電紡絲程序製成離子交換濾材的可行性。探討內容包括比較聚苯乙烯與保麗龍為材料再製纖維濾材,靜電紡絲程序考慮參數包括溶解聚苯乙烯及保麗龍溶劑中四氫呋喃(THF)和二甲基甲酰胺(DMF)的混合比例,聚合物溶液濃度、聚合物溶液注射流量、施加電壓與噴頭與收集板距離。以小於300nm靜電紡纖維直徑為目標,最佳靜電紡絲程序操作條件為聚苯乙烯溶液濃度50 g/l、供電電壓12 KV、進料速率1.0 ml/h及間隙距離5 cm,得到靜電紡絲纖維直徑為253 nm,將相同條件應用於保麗龍得到靜電紡絲纖維直徑為443 nm。再以纖維浸泡的磺酸化程序使磺酸根基接附於纖維支鏈,使纖維活化具離子交換能力及重金屬去除能力。纖維樣品依不同磺酸化時間(5、10、20、40和80分鐘),依序浸泡在98%、70%、50%、25%和5%的硫酸溶液,最後在DI水中洗滌,利用傅立葉紅外線光譜儀(FTIR)鑑定纖維支鏈上的磺酸根基,確認聚苯乙烯及保麗龍靜電紡絲纖維在磺酸化時間為10分鐘及20分鐘SO3H接附程度最明顯。透過酸鹼滴定實驗得到靜電紡絲纖維的離子交換能力(IEC),得出聚苯乙烯及保麗龍靜電紡絲纖維最佳離子交換能力發生在磺酸化時間10分鐘,分別為32.91與27.65(m.mol/g) 。最後再進行靜電紡絲纖維對水溶液中銅離子的去除實驗,得出聚苯乙烯及保麗龍靜電紡絲纖維的最佳銅離子去除能力,分別發生在磺酸化時間20分鐘及10分鐘,銅離子去除率分別為18.17與57.09(mg Cu2+/g)。本研究證實以回收保麗龍作為靜電紡絲纖維材料,所製作的靜電紡絲纖維經磺酸化後可作為離子交換濾材,用於去除水中的重金屬。 |

This study is focused on the Feasibility study of applying electrospinning to recycle waste polystyrene into ion exchange membrane. Discussion includes comparison of polystyrene and waste polystyrene materials reconstituted fiber filters. Electrospinning program parameters considered include dissolved polystyrene and waste polystyrene solvent tetrahydrofuran (THF) and dimethylformamide (DMF) the mixing ratio, polymer concentration in the solution, the polymer solution injection flow rate, applied voltage and the needle and from the collection plate. Electrospinning fibers of less than 300nm in diameter is target. Through the results, Polymer solution concentration 50 g / l, supply voltage 12 KV, flow rate 1.0 ml / h and the gap distance 5 cm is the Polystyrene electrospun fiber optimum operating conditions. Get polystyrene electrospun fiber diameter of 253 nm. The above polystyrene optimum operating conditions applied directly waste polystyrene, Get electrospun fiber diameter of 443 nm. Use immersion sulfonated program make sulfonate attached to the fiber branched. The fibers will have an ion exchange capacity and heavy metal removal capability. Sulfonated fiber samples depending on the time (5,10,20,40 and 80 minutes) sequentially immersed in 98%, 70%, 50%, 25% and 5% sulfuric acid solution. The final rinse was done in DI water.Fourier infrared spectroscopy (FTIR) to identify sulfonate on fiber branched chain. Polystyrene and waste polystyrene electrospun fibers sulfonate time was 10 minutes and 20 minutes SO3H then attach the most obvious level. By acid-base titration to calculate the ion exchange capacity (IEC). Polystyrene and waste polystyrene electrospun fiber optimum ion exchange capacity of sulfonated occurred 10 minutes, respectively, 32.91 and 27.65 (m.mol / g). Finally, electrostatic spinning fiber removal experiment copper ions in aqueous solution, obtained polystyrene and Styrofoam electrospun fibers optimum copper ion removal capacity. Which occurred at 20 minutes and sulfonated 10 minutes, copper ion removal rates were 18.17 and 57.09 (mg Cu2 + / g).This study demonstrates that in order to recover waste polystyrene as electrostatic spinning fiber materials, After the manufactured electrospun fibers with sulfonated.It can be used as ion exchange filters, for the removal of heavy metals in water. |
