- ... The presence of contaminants in potable water is a cause of worldwide concern. In particular, the presence of metals such as arsenic, lead, cadmium, mercury, chromium can affect human health. There is thus a need for advanced techniques of water decontamination. Adsorbents based on cerium dioxide (CeO₂), also named ‘ceria,’ have been used to remove contaminants such as arsenic, fluoride, lead and ...

- ... Glyphosate is a broad-spectrum toxic herbicide that has entered the environment. Advanced oxidation processes efficiently remove various persistent organic contaminants. In particular, generation of sulfate radicals based on catalytic sulfite oxidation is promising, but previously used Fe(II/III) catalysts have reduced activity at pH above 4 due to precipitative deactivation. Therefore, here we te ...
