Abstract:Phosphonate antiscalants are commonly used in reverse osmosis (RO) membrane desalination to prevent fouling by mineral scale. However, due to its adverse effects on the ecosystem and the removal of hardness from RO concentrates, it is necessary to remove phosphonate antiscalants before RO concentrates disposal. In this work, using powder activated carbon (PAC) as carrier, La/FeOOH@PAC composite material was prepared via co-precipitation of lanthanum hydroxide and iron oxyhydroxide. The synergistic effect of La… Show more
