In recent times, pomegranate-derived compounds have been proven to sluggish mobile growing older, shield unborn infants’ brains, and function components in higher automotive supplies. Now, they’ve additionally been used to take away prescribed drugs from wastewater.
Prescribed drugs usually enter municipal wastewater streams as they’re handed in sufferers’ urine. Sewage remedy crops do assist decrease their ranges, however a certain quantity of the medicine nonetheless find yourself being launched into native waterways together with the handled water. They might then hurt aquatic life and doubtlessly even folks.
Beforehand, some teams have explored using nanoporous supplies often called metal-organic frameworks (MOFs) to extra successfully filter prescribed drugs out of wastewater. Whereas the supplies have proven promise, the metallic ions and artificial natural molecules utilized in them are sometimes expensive and/or briefly provide.
With drawbacks resembling these in thoughts, scientists from Sweden’s Stockholm College appeared to a naturally occurring molecule known as ellagic acid … and sure, it is present in pomegranates, amongst different locations.
“Ellagic acid is among the essential constructing models of naturally occurring polyphenols often called tannins, that are frequent in fruits, berries, nuts, and tree bark,” stated PhD scholar Erik Svensson Grape. “By combining ellagic acid, which was extracted from both pomegranate peel or tree bark, with zirconium ions, we developed a brand new extremely porous MOF which we named SU-102.”

When SU-102 was examined on water that had already been handled at an area wastewater facility, it eliminated a major quantity of the leftover pharmaceutical pollution that had been missed. And as an added bonus, in a course of often called photodegradation, the fabric broke these pollution down into innocuous components when uncovered to ultraviolet gentle.
“This has been a really thrilling venture as we acquired the chance to work immediately with water samples from the remedy plant,” stated Grape. “We hope someday that SU-102 can be used on an even bigger scale and likewise for different environmental purposes.”
A paper on the analysis was lately revealed within the journal Nature Water.
