The plot of copper extraction against pH is shown in Fig. 2. At a pH below 0.5, the copper extraction increased quickly with increasing pH. At a pH above 0.5, the copper extraction increased slowly with increasing pH, indicating that the copper extraction was close to the full capacity of the extractant.
