摘要：

Extraction of platinum group metals and gold from hydrochloric acid solutions with calix[4]arenamines (CAA) and calix[n]arene thioethers (n = 4, 6; CTE) was studied. The high macrocyclic effects (10(2)-10(3)) are due to chelation between metals and the donor centers of macrocycles in the systems CAA-Pd and CTE-Ag, Pt-II, and Pt-IV. New CAA-based extracting systems for collective extraction of Pd, Pt, Au, Ir, and Rh and new CTE-based systems for separation of Au and Pd from Ag and Pt were justified.
