2018-10-25 · It was found that the increase of L concentration had a positive effect on the nickel extraction when only extractant L was used. But the extraction percentage of nickel was still very low and no more than 10%, which indicated minimum extractability of L in the simulation electroplating wastewater (Fig. 3a). Apparently, D2EHPA provided the higher extraction percentages of nickel and magnesium
