Extraction of Pd(ii) and Pt(ii) from aqueous …

The extraction ability of 1,3-diaminocalix[4]arene (2: H 2 L) toward platinum group metals (PGMs) has been investigated, which revealed that 2 is able to extract Pd(II) and Pt(II) from hydrochloric acid via different extraction modes.The extraction species for Pd(II) and Pt(II) are [PdL] and [Pt 2 Cl 6 (H 3 L) 2], respectively, as evidenced by equilibrium analysis and X-ray crystallography.
