The purpose of this paper is to present the IZO application that calculates and visualizes coefficients of adsorption isotherms according to Freundlich, Langmuir, and BET in a classic and linear system, in a simple communicative way. The application also calculates the working time of the adsorption bed based on the transformation of the mass balance equation, and according to the Zuchowicki, Zabieziński, Tichonow, and the Bohart-Adams equations. The laboratory tests of the adsorption process of leachate from a municipal landfill on selected active coals ORGANOSORB 10, DESOTEK, and BA-10, were conducted to check the program for accuracy. Results of tests confirm that the linearization method of the calculation of adsorption isotherms coefficients, used in the IZO application, gives sufficient accuracy and may be used as an alternative of, e.g., the nonlinear estimation method.

Practical Recommendations

The quantitative relationship between the plate theory variant model of equilibrium adsorption in which time is the only independent variable and the theory of ideal chromatogaphy has been evaluated. It has been shown that an approach to ideal conditions depends directly on an increase in the relative (or absolute) length of the column. Practical recommendations on the choice and assessment of conditions to verify the measurement of adsorption isotherms and on the calculation of chromatographic processes in accordance with the theory of ideal chromatography are given.

Theoretical Results

Breakthrough curves of CF3Cl on carbon black and of cyclo-hexane on active charcoal have been measured under elution adsorption dynamic conditions. For linear and non-linear adsorption dynamic modes, the experimental data and theoretical results calculated according to the layer of equilibrium adsorption (LEA) model closely coincide.
