Recovery and Processing of Gravimetric Sorption Data

Original language description

The computational procedure is based on modelling and simulation, control theory, experimental identification, digital signal filtering and processing and nonlinear optimization. The standard theoretical model describing the dynamics of sorption of organic vapours in polymeric membranes is modified in view of dynamic characteristics of the measuring chamber. Calculated values of vapour pressure after its injection into the measuring chamber fit then to measured data better. Random noise is eliminated from effective signal by use of a low-pass Butterworth digital filter with a suitably chosen cut-off frequency. Parameters of mathematical model (diffusion coefficient, time constant of the measuring chamber, the initial and final value of the signal and its time delay) are calculated using the Nelder-Mead flexible polyhedron method.
