ΔpH = ΔpHoexp(-ktm),
где ΔpH - отклонение величины pH от оптимального значения;
ΔpHo - максимальное отклонение величины pH от оптимального значения в начальный момент времени;
t - время экстракции;
k, m - константы, определяемые по экспериментальным данным.The method of extraction of ions from solutions, including the processing of the extractant and the solution, the contact of the extractant and the solution, characterized in that during the extraction process the deviation of the pH of extraction from the optimal value depending on the extraction time is maintained according to the following relationship:
ΔpH = ΔpH o exp (-kt m ),
where ΔpH is the deviation of the pH value from the optimal value;
ΔpH o - the maximum deviation of pH from the optimal value at the initial moment of time;
t is the extraction time;
k, m are constants determined from experimental data.
