Title: REMOVAL OF SULFUR SUBSTANCES FROM AN AQUEOUS MEDIUM WITH A SOLID MATERIAL
Abstract:
The present invention relates to a water treatment method for removing sulfur substances using a solid material comprising 2-amino-2-deoxy-d-glucopyranose structural units, wherein the solid material is combined with an acidic aqueous medium containing sulfur substances so that the negatively charged sulfur substances can be bound to the solid material and subsequently be removed from the aqueous medium by separating the solid material. The present invention can be used to remove sulfur substances such as sulfate, bisulfate, sulfite, bisulfite, metabisulfite, sulfide, bisulfide and thiosulfate from an aqueous medium.
