Константы скорости реакции увеличиваются с 0,064 ± 0,005 до 0,089 ± 0,006 сут-1 при возрастании температуры с 10 до 20 °С, а периоды полупревращения соответственно снижаются с 10,8±0,8 до 7,8± 0,6 суток. Кинетические и активационные параметры позволяют рассчитать скорость разложения синтетических линейных АПАВ в природной воде при изменении условий в окружающей среде.</p></abstract><trans-abstract xml:lang="en"><p>The method of laboratory modeling was used to determine the rate constants, half-transformation periods, temperature coefficient, and free activation energy and activation enthalpy of the reaction of biochemical decomposition of sodium dodecyl sulfate in the water of the Petrozavodsk Bay of Lake Onega at different temperatures. The reaction rate constants increase from 0.064 ± 0.005 to 0.089 ± 0.006 day-1 with an increase in temperature from 10 to 20 °C, and the half-life periods respectively decrease from 10.8 ± 0.8 to 7.8 ± 0.6 days. Kinetic and activation parameters make it possible to calculate the rate of decomposition of synthetic linear anionic surfactants in natural water under changes in environmental conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синтетические поверхностно-активные вещества</kwd><kwd>лабораторное моделирование</kwd><kwd>самоочищение водоемов</kwd><kwd>переходное состояние</kwd><kwd>свободная энергия активации</kwd><kwd>энтальпия активации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>synthetic surfactants</kwd><kwd>laboratory modeling</kwd><kwd>self-purification of water bodies</kwd><kwd>transition state</kwd><kwd>free activation energy</kwd><kwd>activation enthalpy</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">Manousaki E., Prillakis E., Kalogerakis N., Mantzavinos D.
