use of the ceramic industry by-product (sic). The present invention concerns the use of the ceramic industry by-product, also commonly referred to as tile or brick shard or ceramic tile shard, for use as an adsorbent and softener for cation and anion contaminated areas. such as: zn, cu, cd, bp, as, and others. Because it is a clayey material, containing in its matrix tectosilicates, phyllosilicates, oxides and other minerals, originating from the raw material or transformed during heat treatment, the ceramic industry by-product is an adsorbent and softener capable of retaining the toxic elements, providing, when applied to aqueous solutions and contaminated soils, a lower toxicity of contaminants and a better environment for plant growth and development. the inorganic elements, being sorbed in a solid matrix, will become unavailable to be absorbed by plants, to be transferred to the trophic chain or to be leached to the groundwater, which substantially reduces environmental contamination and eutrophication. waters in the case of phosphorus. |
