Ammonium persulfate (APS) is the inorganic compound with the formula (NH 4) 2 S 2 O 8.It is a colourless (white) salt that is highly soluble in water, much more so than the related potassium salt. It is a strong oxidizing agent that is used in polymer chemistry, as an etchant, and as a cleaning and bleaching agent.. The dissolution of the salt in water is an endothermic process

The recovery of neodymium from scrap Nd-Fe-B magnets was developed using a novel eco-friendly alternative with ammonium persulfate. Optimal conditions were established as (NH 4) 2 S 2 O 8 concentration of 1.3 M, a temperature of 75 °C and L/S ratio of 50 mL/g. These conditions allowed 98% of neodymium recovery after 15 min of reaction time.
