The paper presents the results of the study of the
statics of adsorption of surface-active substances from model
solutions by activated carbon and zeolite. The results of
photometric determination of the concentration of anionic
surfactants before and after adsorption are presented. The
results of adsorption capacity calculations are presented. The
experimental results using the program (Langmuir 1.03) were
numerically calculated. Sorption isotherms of sodium dodecyl
sulfate indicate the mechanism of monomolecular physical
adsorption. A good convergence of experimental data and
theoretical calculations were established, the coefficient of
determination R2>0.9, the value of the Chebyshev criterion
9·10-4... 2·10-4, and the root mean square deviation equal to 0
were established.
