In the presence of CTMAB,the reaction of pheylflurone with Ge(Ⅳ) to form a red complex is studied by FIA Spectrophotometry.The method was applied to the determination of germanium in green tea and satisfactory results were obtained.The wavelength of maximum absorbance of this complex was at 333nm,detection limit was 0.1 μg/ml and Beer’s law was obeyed in the concentration range of 0μg/ml～10μg/ml.The mean recovery is 94.02% and relative standard deviation is less than 0.54%.
Investigated in this paper was the absorbing and distributing of nicotine in the tobacco and filter tip during the course of smoking, gas Chromatography being used.The experimental result indicated that the nicotine in the suck part of cigarette was absorbed by tobacco and filter tip together.Before the cigarette was sucked to 3/4,the nicotine in the left tobacco and filter tip being accounted to about 90% of the total,the part entered into the body is less than 10%. But if the cigarette was sucked to the end,about 50% of the whole nicotine would entered into the body.
