Method for evaluating the kinetics of dynamic gas extraction

  • Ladislav Zelinka
Original Papers


New methods have been developed for the study of the kinetics of the dynamic gas extraction process based on instrumental recording of the extraction curve and division into half-lives whose temporal values can be employed for the calculation of the distribution coefficient. The dependence of this process on the thermodynamical system as well as on instrumental factors for the testing of field equipment was determined using toluene dissolved in water, by means of which in connection with sorption process isolation, enrichment and preservation of volatile organic compounds in samples were achieved.
