PROCESS FOR THE REMOVAL OF ENDOCRINE DISRUPTING COMPOUNDS

The present invention relates to the removal of endocrine disrupting compounds from an aqueous medium by adding surface-reacted natural calcium carbonate or an aqueous suspension comprising surface-reacted calcium carbonate and having a pH greater than 6.0 measured at 20 °C, to the medium, wherein t...

Beschreibung
Zusammenfassung:	The present invention relates to the removal of endocrine disrupting compounds from an aqueous medium by adding surface-reacted natural calcium carbonate or an aqueous suspension comprising surface-reacted calcium carbonate and having a pH greater than 6.0 measured at 20 °C, to the medium, wherein the surface-reacted calcium carbonate is a reaction product of natural calcium carbonate with carbon dioxide and one or more acids, the use of the surface-reacted natural calcium carbonate for the removal of endocrine disrupting compounds, as well as to a combination of a surface-reacted natural calcium carbonate and activated carbon for the removal of endocrine disrupting compounds.
