Peroxygen sodium percarbonate

Separate peroxygen bleaches, hydrogen peroxide, or its sources like sodium perborate or sodium percarbonate from water to prevent premature reaction, such as by suspending the solids between surfactant lamellae in the structured liquid. 

Peroxygens are used widely throughout industry for the safe and effective treatment of cyanide in process and waste waters. Under alkaline conditions, cyanide is efficiently oxidized to the much less toxic cyanate by peroxygens such as hydrogen peroxide, Caro s acid and sodium percarbonate.27 The cyanate slowly hydrolyses to ammonia and bicarbonate (Figure 5.5).
