中文摘要 | 天然及合成高分子材料如改質澱粉、聚乙烯醇及亞克力等,被應用於紡織工業上作為經紗上漿劑,因此紡織廠排放的廢水中含有大量的漿料。上述這些漿料中,特別是合成漿料最不容易被分解,因此基於環保的考量,全世界正努力地研究發展生物可分解型高分子漿料,但至今大多數研究仍著重於合成高分子材料,而較少探討於高分子化學結構與生物分解性之關係。 本研究利用批式培養法,來評估幾種天然及合成漿料之生物分解性,使用改質澱粉(S1及S2)、聚乙烯醇(P1及P2)及亞克力(A1及A2)當作基質,並添加0.1%酵母茵萃取物及Polyseed®菌種。其中Polyseed®為一種專門測試BOD值的環境菌株。在室溫下培餐60-84天,籍由量測漿料的COD值變化來評估生物分解性。其結果顯示,0.1%Sl及S2在25-35天內即可被分解,隨後再添加S1及S2放入培養液中其分解的速率仍然維持一樣,PVA及亞克力在經過83天的培養不被分解,S2與P1的混合物可去除一半以本的COD。 |
英文摘要 | Natural and synthetic polymeric materials such as modified starch, PYA, acrylic have been used as warp sizes in textile industry. The waste load from the textile finishing mills contains significant amount of the sizing agents. Most sizing agents, especially those synthetic ones are not easy to be degraded. There is a world-wide research effort to develop biodegradable polymers as a waste-management option for polymers in the environment. However, most of the effort was focus on synthesis oriented of polymers until now. Quit few attention was paid to understand the relationship between structure-activity and biodegradability of the polymers. In this study batch culture experiments were performed to assess biodegradability of several natural and synthetic polymeric materials. Modified starch (S1 and S2), polyvinyl alcohol (P1 and P2), and acrylic (A1 and A2) polymers were used as the substrates. Batch experiments were performed in 120-ml flasks containing 100 ml of defined medium supplemented with 0.1 % yeast extract. Polyseed®, a broad spectrum of specialized bacteria used for the BOD test, was used as the inoculum. Flasks of sterile culture medium without inoculum were used as the controls. The flasks were incubated at room temperature for 60-84 days. Biodegradation was determined by following bacterial growth, chemical oxygen demand (COD) removal. Results showed that 0.1 % S1 and S2 were degraded within 25 days and 35 days respectively. On a subsequent addition of S1 and S2 into the cultures, respectively, the degradation rates of S1 and S2 remained the same. PV A and acrylics polymers remained persistent during 83 days incubation. Less than half of the COD was removed in cell cultures amended with S2 and P1. There were no significant changes of polymers in sterile controls during the sampling period. |
