EFFERVESCENT ZERO-VALENT IRON COMPOSITIONS AND METHOD OF REMEDIATION OF POLLUTANTS FROM AQUEOUS SOLUTIONS

摘要

: The present invention provides effervescent compositions, in particular for remediation of aqueous solutions, containing zero-valent iron particles, an acid in powder form, and an alkali metal bicarbonate or carbonate. Said compositions are easy to manufacture, cost effective, stable to store and highly active in remediation of pollutants, especially of heavy metals and organic compounds, from aqueous solutions by reduction. They can be combined with further components when other processes, e.g. absorption, are required for the optimal remediation ability.
