21. The adsorption isotherm of Fig. 4b, expressed in yield versus residual gold concentration at saturated adsorption, does not include data points of initial concentrations below 20 ppm because, as the rapid adsorption of all the gold for the 1 ppm gold solution shown in Fig. 4a, the volume of the solution required for such measurement is beyond the scale achievable in a laboratory.
