Adsorption of fluoride from water by surface-functionalized polyurethane foam
Surface-functionalized polyurethane foam (SPUF) showed an exceptionally high adsorption potential for defluoridation of drinking water. Kinetic experiments of fluoride adsorption on SPUF demonstrated quick adsorption in first 60 min and then achieved maximum adsorption (7.8 mg g−1). The adsorption isotherm was described using Bradley equation. The adsorption capacity of SPUF was significantly ...

Effect of ion (Al, Fe and Zn) co-doped TiO2 nanotubes on photocatalytic degradation of humic acids under UV/ozonation for drinking water purification
O3/UV/TiO2 was used to effectively decompose humic acids (HAs) in drinking water. A series of Al-doped, Fe-doped, Zn-doped and co-doped TiO2 nanotubes were successfully synthesized by a hydrothermal method. According to the characterization of ion-doped TiO2 nanotubes, Al3+ and Fe3+ ions occupied substitutional positions in the crystal lattice, and Zn2+ ions were partially dispersed in the ...

The integrated water cycle: does its value outweigh its cost?
The integral water cycle is essential in human development. Its multiple applications give it a leading role and, therefore, make water a resource that must be protected to ensure sustainability. However, according to Idrica, there are still those who do not appreciate its importance, focusing on factors such as price at the expense of the value that proper investment holds. Nowadays, society is ...

Ozone FAQ
What is Ozone? An ozone molecule is nothing more than an oxygen molecule that has received an extra oxygen atom. nature constantly produces ozone. A well-known example is the ozone layer, created by UV rays (UV) emitted by the sun. Also, nature produces ozone during storms and waterfalls. When one speaks of ozone, the above-mentioned examples are immediately associated with it. In contrast, it ...

Mangrove coasts: a muddy story (Part 3)
In my first blog, I introduced the term “ecosystem services”, which has become a popular way to refer to the value of ecosystems. This is an important concept as it provides a counter-argument to the often narrow-minded and short-eyed approach of economics. The traditional economic focus on “How much can I earn today?” neglects the long-term consequences of short-term ...

Potential Drinking Water Contamination Analyzed
A comparison of more than 100 large US cities showed pollution from point and nonpoint sources Too often, surveys of water quality in the United States have been regionally inconsistent patchworks that neglect many unregulated contaminants. A granular study of potential source water contamination in the largest cities in the U.S. has been lacking. New research in the journal Nature, however, ...
