Abstract:	現今世界各地由於污染的問題日趨嚴重而紡織業首當其衝是染料與染色廢水的問題。另外，新功能材料的研發日新月異。因此，本研究嘗試從天然植物中尋求可替代物質。同時，由於天然可替代物質具有節約能源與達到工業減廢的功能與優點，而且亦將成為未來發展的趨勢。因此本研究係以生蘆薈、烘乾後之蘆薈和曝曬後之蘆薈為樣本，並分別以蒸餾水與不同有機溶劑將研磨後之各種蘆薈樣本溶解其中可溶之物質，並加以過濾之。然後，再以紫外線－可見光（簡稱UV）分光光譜儀測定各種蘆薈溶液與溶劑之光譜圖，並藉著各個光譜圖來分析在不同或相同溶劑下之各種蘆薈UV吸收光譜之特性。由實驗結果顯示以有機溶劑正己醇有較佳之溶解效果，並依其蘆薈UV吸收光譜可發現似乎有特殊物質的存在，而且可供深入其研究之參考。 Nowadays, the environmental pollution is an extremely important event in each industry. And, the synthesis of dyes is one of the most important pollution sources in chemistry or textile industry. In addition, more and more new functional materials are made. Hence it is more and more important to use the natural dyes instead of the synthesized dyes, and that would become a trend in the future. In this study, the raw and dried (by sunlight and oven respectively) leaves of aloe are employed as the specimens. And the UV absorption spectra of these specimens are investigated. The results show that there exist specific and important UV absorption wavelengths for those phthalocyanine derivatives, normally as useful pigments, and the other special substance. Further studies are needed to verify this finding.
