Abstract
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.
