Apr 01, 2019· Up to10%cash back· Efficient Pb leaching was achieved in HClcomplete extraction was provided by 3 and 5 M HCl, whereas H 2 SO 4 did not extract Pb due to PbSO 4 formation; similarly, in oxalic acid, Pb precipitated as PbC 2 O 4. Ethaline could extract 50% of Pb with high selectivity towards Fe.
