USE OF ALKALINE EARTH PEROXIDES FOR IMMOBILISING PHOSPHATE IN WATERS, SOILS, SEDIMENTS AND/OR SLUDGES

摘要

A method is providing for treating waters, such as standing and flowing waters and waste waters, soils, sediments and/or silts. At least one alkaline earth metal peroxide is brought into contact with such waters or the like, especially to effect immobilization of phosphates and heavy metals except manganese and iron therein.
