Each row in the table represents an experimental subgroup, whereby a single ionic metal per subgroup was applied. The three parameters (a, b, c), the significance levels (p-values) by Student’s t-tests and the correlation coefficients (r2-values) are given for each ionic metal applied in a mixture (1,000 µg/l per metal) after fitting the residual concentrations (y) of each metal ion in water by the generalized function y = (a + b*x)/(1 + c*x) depending on incubation duration (x, 0–48 h). Standard deviations of measurements at each data point were less than 5%. The asterisk mark (*) indicates the highest elimination of the respective metal ion from the aqueous phase.
