Streszczenie: The paper presents a model of physico-chemical processes in aquatic ecosystems, utilizing mass balance equations for multicomponent two-phase systems. This model aims to provide a comprehensive understanding of the interactions and dynamics within aquatic environments. It presents original mass balance equations within the residual concentration method to analyze thermodynamic functions for various natural chemical equilibria, described by the developed generalized equations. By incorporating mass balance equations, the study addresses the distribution and transformation of various chemical species between natural waters and sediment phases. The approach allows for the simulation of complex processes such as adsorption, desorption, and chemical reactions in a detailed and systematic manner. The method demonstrates the ability to handle simultaneous formation of multiple chemical species and derive specific thermodynamic relationships. It provides a comprehensive analysis of thermodynamic conditions, estimating solid phase quantities based on initial composition and pH values. Applied to several real systems, the approach shows strong agreement with experimental findings, validating its robustness and applicability. The developed model can be used to predict the behavior of pollutants, nutrients, and other substances in aquatic ecosystems, offering valuable insights for environmental management and conservation efforts.
