Степень адсорбции аммония во всех почвах можно лучше всего описать при помощи псевдо второго порядка, степенной функции и упрощенных уравнений Эловича.</p></abstract><trans-abstract xml:lang="en"><p>The study of adsorption kinetics is very useful for understanding the mechanisms that are involved. In order to predict the mechanism involved during the present sorption process and the potential rate controlling steps such as mass transport, pore diffusion and chemical reaction processes, several kinetic models were used to fit the experimental data, namely, zero-order, first-order, pseudo-second-order, simplified Elovich, parabolic diffusion and power function models. At the present study, an ammonium adsorption kinetic experiment was conducted using solution containing 100 mg/l of ammonium chloride at the times of 0.25 to 384 h. Kinetic equations for ammonium adsorption were evaluated by comparing coefficients of determination (r2) and standard errors of estimate (SE) for each equation, which were determined by least square regression analysis. The results of adsorption kinetic study showed that ammonium is adsorbed fast within the first hours, but with elapsing the time, it will be slow. The most ammonium adsorption was in Kordkoy soil and the lowest one was observed in the Houttan soil 2. The rates of ammonium adsorption in all soils could be best described by the pseudo second order, power function and simplified Elovich equations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Adsorption</kwd><kwd>ammonium</kwd><kwd>kinetic</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Azizian, A., 2004.
