Method and system for cross-marketing products and services over a distributed communication network

A method is described for precious metal recovery from acidic precious metal-cyanide solutions by means of a weakly-basic anion-exchange material comprising a polymeric felt incorporating radiation-grafted pyridinyl functional groups.

Gold recovery process

A method is described for metal recovery from basic ammoniated metal solutions by means of a weakly-acidic cation-exchange material comprising a polymeric felt incorporating radiation-grafted monomers comprising carboxylic acid functional groups.

Copper recovery process

This disclosure is directed to improved redox type electrochemical cells, preferably those of the iron (+3)/iron (+2) or chromium (+3)/iron (+2) electrolyte variety, incorporating polymeric, ion-exchange separator membranes produced by radiation grafting techniques.

Separator membranes for redox-type electrochemical cells

This disclosure is directed to improved redox type electrochemical cells, preferably those of the iron (+3)/iron (+2) electrolyte variety, incorporating polymeric, ion-exchange separator membranes produced by radiation grafting techniques.

This invention relates to an irradiation grafting process for preparing separator membranes for use in electrochemical cells, comprising contacting a polymeric base film with an aqueous solution of a hypophilic monomer and a polymerization retardant; and irradiating, said contacted film to form a graft membrane having low electrical resistivity and having monomer molecules uniformly grafted thereon.

Gamma radiation grafting process for preparing separator membranes for

This disclosure is directed to polymer membranes to be used in electrochemical cells and improved processes for producing the same. The membranes are produced by radiation grafting techniques. The improved process includes the grafting of a hydrophilic monomer, such as methacrylic acid in a chlorinated organic solvent onto an inert base film such as polyethylene. The process also includes but is not limited to the use of inhibitors to limit homopolymerization of a grafting material, as well as emulsifying agents to lower the electrolytic resistance of the finished membrane.

Separator membranes for electrochemical cells

This disclosure is directed to fluorocarbon polymers, polymeric membranes, and electrochemical cells and processes. The polymers and membranes are produced by radiation techniques to provide improved products. For example, .alpha.,.beta.,.beta.-trifluorostyrene in an inert organic solvent is grafted onto an inert film, such as tetrafluoroethylene-hexafluoropropylene copolymer, by irradiation, i.e. with Co-60 gamma radiation at a dose of several Mrad. The grafted film is then sulfonated, preferably in a chlorosulfonic acid bath. The resulting film is useful as a membrane or diaphragm in various electrochemical cells such as chlor-alkali or fuel cells.
