碩士 === 嘉南藥理科技大學 === 環境工程與科學系碩士班 === 95 === 4-Nitrophenol sorted out as the intermediate poisonous substance, will be drawn use of the loose weed killer and fragrant clan hydrocarbon to discharge to the sand by second photochemical reaction via the bar. Research this department is it resolve 4-NP sand that phenol polluted to oxidize with ozone, and direct against the moisture content of different sand (8%, 5% and 3%) And the flow of different ozone (108 ml/min, 262 ml/min and 415 ml/min) ,Degrade four 4-NP efficiency and carry on the discussion to the ozone. The result shows, being moisture content getting high, sand degrade four 4-NP fine result have (8% sand moisture content ozone degrade to four nitre base phenol efficiency can up to 100% by ozone, 5% sand moisture content can up to 93.6% but 3% sand moisture content can up to 88 equally equally) ,And this response reacts (pseudo-first-order reaction) in order to be like one steps . And the the slower one of flow of ozone, the result of degrading four 4-NP of ozone is better. In addition, from keep a grip on section system can find, offer enough ozone, four 4-NP of sand will is it react to produce with ozone at once, therefore can know, the ozone degrades four 4-NP and is spread and controlled by qualities.
