碩士 === 國立高雄師範大學 === 化學系 === 95 === The research analysis procedures include three steps: sampling of mud volcanoes, tube column cleanup and instrument examination. The research samples come from Wushangding mud volcano on the back of the Yanchao Campus of the National Kaohsiung Normal University, each sample contains liquid and solid volcano mud, the proportion of liquid and solid varies from each sampling. 　　After sampling, we use the Liquid-Liquid Extraction Method to extract the liquid part of the samples, the Sonication Extraction Method to extract the solid part of the samples, and the Soxhlet Extraction Method to extract the liquid and solid parts of the samples. The extract products from the three above mentioned methods after extracting from the mud volcanoes, will be purified with hexane,hexane/ether (9:1,v/v) and Methyl alcohol/ Methylene chloride (1:1,v/v) through oxidized aluminum tube column, then examined with the Gas Chromatograph/Mass Selective Detector (GC-MS). As result of examination through the Gas Chromatograph/Mass Selective Detector (GC-MS), the organic substances of the mud volcano samples are primarily n-alkane and phenols, and the samples are strongly influenced by the weather, the samples collected after raining days, even after long time of extracting with the Soxhlet Extraction Method cannot give a satisfactory result after examination, it is clear that the rain water has had extremely obvious dilution effect. 　　After comparing the examination result with the common biological indicators, we notice that the organic substances in the samples collected from the mud volcanoes mainly come from land higher plants and the result of the redeposit after washing out the upstream’s deposit, this conforms the geographic location in the mountains and the luxuriant plants in the region, hoping this research result can provide reference values for the future land developers, in order to take advantage of the land as much as possible, aw well as a perfect planning and conservation of the mud volcano.
