| Abstract: | In this paper, a method of using the dynamic stripping technique and gas chromarogrphy is presented to determine the dissolved methane concentration in seawater. Its determination in four steps-bubbling, trapping(absorbing), desorbing and detecting and the bubbling time, bubbling gas now rate, trapping temperature and relative factors which affect the determination were discussed in derail. The resultS show that this analytical method is rapid, has good precision and high sensitivity and can be widely used in situ at sea for determining the dissolved methane in sea water. |
