Abstract: A method of chemically stabilizing multivalent oxyanions in residue materials such as wastes from glass manufacturing facilities which method involves adding to the residue material cement, lime and aluminum sulfate to form a clay-like material having a low leachability and permeability to water. Calcium polysulfide or other sulfide bearing materials can also be added to assist in stabilizing multivalent oxyanions by adjusting the oxidation-reduction potential of the stabilized waste matrix.

Abstract: A calcium-sodium polysulfide chemical reagent and methods for producing the reagent. The reagent is a blend of calcium polysulfide and sodium polysulfide that can be prepared using various types, sources and ratios of lime, elemental sulfur and sulfide ion using either virgin or waste materials. The reagent is amenable to inexpensive and high rate production methods at ambient or warmer temperatures. The reagent can be used to precipitate metals from wastewater, stabilize hexavalent chrome in hazardous waste residues, remove mercury from coal fired power plants, and as an electrolyte in large-scale bromide/polysulfide electrical storage batteries.
