adszorbereken

Adsorbereken is a term from Dutch literature used to describe the process and methodology of calculating adsorption properties of materials. It combines adsorberen, meaning to adsorb, with berekenen, meaning to calculate. In practice, adszorbereken covers fitting experimental data to adsorption models to quantify capacity and energetics, as well as related kinetic and thermodynamic analyses.

Common models used in adszorbereken include Langmuir, Freundlich, and BET isotherms to estimate parameters such as maximum adsorption capacity (qmax), affinity constants, and the specific surface area of a material. Kinetic analyses employ models like pseudo-first-order and pseudo-second-order to describe uptake rates and to infer mechanism. Temperature-dependent data allow rough thermodynamic insights, such as adsorption enthalpy and spontaneity.

Data for adszorbereken typically come from gas- or liquid-phase adsorption experiments, where uptake is measured as a function of pressure at a fixed temperature or as a function of time at fixed conditions. Analysis often relies on nonlinear regression, alongside diagnostic plots and goodness-of-fit criteria to compare models and parameter stability. Software tools commonly used include regression packages and isotherm fitting routines.

Applications of adszorbereken span material science and environmental engineering, including the design of activated carbons, zeolites, and metal-organic frameworks for catalysis, separations, gas capture, and water treatment. Limitations arise from model assumptions (such as surface homogeneity in Langmuir or ideal porosity in BET), the presence of multilayer adsorption, and diffusion limitations that can complicate interpretation.
