- Abstract:
- ... 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 ...

- Abstract:
- ... Bisenols and its derivatives are attractive heterocyclic compounds exhibiting a wide range of biological properties, including anticancer, antipyretic and antimicrobial characteristics. Many catalytic systems have been reported to enhance the synthesis of bisenols, but these catalytic systems suffer from several drawbacks, such as the use of external metals, expensive and toxic chemicals. Thus, th ...

- Abstract:
- ... Cyclodextrins are among the most remarkable macrocyclic molecules with significant theoretical and practical impacts in chemistry and biology. Cyclodextrins belong to the family of cage molecules due to their structure, which is composed of a hydrophobic cavity that can encapsulate other molecules. Indeed, the most characteristic feature of these compounds is their ability to form inclusion comple ...

- Abstract:
- ... 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 ...
