摘要: Abstract The ability of aluminium-phosphate-sulfate (APS) phases to preferentially sorb lead and its radionuclides, particularly 210Pb, from metallurgical processing streams has been recently recognised empirically. This suggests that APS minerals may be suitable for the removal environmental anthropogenic processes. We investigated Pb sorption capabilities with different Ca:Sr SO4:PO4 ratios over a range aqueous concentrations (10–1000 ppm) pH (1.5–5.5) typical processes acid drainage conditions. Through combination characterization techniques including electron probe microanalysis, (laser ablation-) inductively coupled plasma mass spectrometry X-ray absorption spectroscopy, we confirm rapid (
