清潔劑一直是不可或缺的民生用品,在工業上的使用也不計其數,合成的清潔劑是由界面活性劑所組成的,其中非離子型界面活性劑的使用量最大,約佔市場的70%。壬基苯酚聚乙氧基醇類(NPnEO)為最常見的非離子型界面活性劑,排入水體經生物分解後所產生的壬基苯酚(Nonylphenol,NP)結構與雌激素相似,累積於生物體內會造成雄性生物雌性化,進而影響到生育、繁殖。
在許多降解壬基苯酚的方法中,多是使用高級氧化法(AOPs)進行降解。本研究以UV直接光解處理壬基苯酚,探討直接光解壬基苯酚之可行性,另外,並探討自然環境中可能影響NP直接光解的因子,溫度、pH值、氯鹽及硫酸鹽等對直接光解之效應。
經實驗證實,壬基苯酚直接光解反應符合一階反應動力式,其k = 0.126 hr-1,反應溫度對於光解之效率並無顯著之影響,硫酸鹽類離子的添加對於光解NP的成效並無顯著之差異,但 鹽則會降低NP直接光解之速率常數。
Detergents are one of the articles for daily use and also are used on long scale in industry. The synthetic detergent is composed of surfactant and other materials. There are three kind of surfactants including cation, anion and non-ionic type. And the utility rate of non-ionic surfactant is about 70%.
NPnEO is the most common non-ionic surfactant, NPnEO drained to water body will be biodegraded to form NP. The structure of NP is similar to estrogen, and it will accumulate in organism to result in feminization of male living and to affect productivity of organism.
Tis study researched the direct photodegradation of NP and its feasibility. And the effect of environmental factors, such as temperature, pH, chloride ion and sulfate ion, also is explored.
Results revealed that the direct photodegradation of NP could be described by first-order rate law, and the k is 0.126 hr-1. It is also found that the temperature and sulfate ion had no significant effect on photodegradation of NP. But the chloride ion decreased the photogradation of NP.
