All chemists are familiar with the litmus test. Like other acid-base indicators, litmus changes color when the pH of a solution changes. The indicator is an example of a "naked-eye" colorimetric ion ...

This study investigated the effect of pH and the presence of coexisting (competitive) anions on the removal of phosphate by titanium mesostructures synthesized using do-or hexadecyltrimethylammonium ...

Ionic interactions in aqueous solutions are fundamental to understanding a plethora of chemical, biological and technological processes. At the heart of these interactions lies the dynamic equilibrium ...

Selective extraction of specific, charge-dense anions from a solution is beneficial, but has been limited in practice by the inability of anion extraction to overcome the Hofmeister bias. In ...

This is a preview. Log in through your library . Abstract The thermodynamic properties of aqueous nitroxyl (HNO) and its anion (NO-) have been revised to show that the ground state of NO- is triplet ...

To preserve life on earth, there need to be efficient purification methods that can separate impurities from water and air. Therefore, for a long time, carbon materials have been used for deodorizing, ...

(Nanowerk Spotlight) Nanotechnology can play an important role in water treatment and an active emerging area of research is the development of novel nanomaterials with increased affinity, capacity, ...

Scientists have successfully synthesized molecular knots and links that could help in understanding biological processes and in detecting environmental pollutants. The international team, including ...
