С позиций современных представлений рассмотрены особенности ионообменных процессов в почвах. Показана эволюция взглядов на природу ионообменной способности почв. Дан критический анализ методов количественного описания обменных процессов в почвах. Показана природа неоднородности обменных центров почвенного поглощающего комплекса и ее влияние на качественные и количественные характеристики ионного обмена в почвах. Сформулированы важнейшие понятия, касающиеся ионообменной способности почв. Рассмотрены механизмы ионообменных процессов в почвах и их физико-химические модели. Существенно расширены возможности описания ионообменных процессов в почвах на основе термодинамических подходов.
It has been considered the peculiarities of ion-exchange processes in soils in the context of modern views. Evolution of the concepts concerning the nature of ion-exchange capacity of the soils has been shown. The methods of qualitative description of ion-exchange equilibrium in soils have been critically analyzed. The character of inhomogeneity of exchange center in soil adsorbing complex and its effect on quantitative and qualitative characteristics of ion exchange in the soils has been disclosed. Basic concepts refferred to ion-exchange capacity of the soils have been stated. It has been studied the mechanisms of ion-exchange processes and their physicochemical models. Thermodynamic approaches affered ample scope for describing ion-exchange processes in soils.
