Method of removing metal values from solution
Abstract
Abstract THE PRESENT INVENTION RELATES TO NEW COMPOUNDS WHICH ARE GRAFFT COPOLYMERS OF CELLULOSE AND POLYACRYLTHIOAMIDE AND GRAFT COPOLYMERS OF SYNTHETIC POLYMERS AND POLYACRYLTHIOAMIDE WITH THE GENERAL FORMULA (A)M-(CH2-CH(-C(=NH)-SH))N WHEREIN A IS CELLULOSE OR A SYNTHETIC POLYMER, M IS THE DEGREE OF POLYMERIZATION OF CELLULOSE AND THE DEGREE OF POLYMERIZATION OF SUCH SYNTHETIC POLYMER RANGING FROM 150 TO 2,000, N IS THE DEGREE OF POLYMERIZATION OF POLYACRYLTHIOAMIDE RANGING FROM 400 TO 4,000, AS WELL AS TO A METHOD OF PRODUCING SAID NEW COMPOUNDS AND TO APPLICATION THEREOF. THE METHOD OF PRODUCING SAID COMPOUNDS RESIDES IN TREATING GRAFT COPOLYMERS OF CELLULOSE AND POLYACRYLONITRILE, OR GRAFT COPOLYMERS OF SYNTHETIC POLYMERS AND POLYACRYLONITRILE, WITH HYDROGEN SULPHIDE OR WITH SALTS OF HYDROSULPHURIC ACID IN AN AQUEOUS OR AN ORGANIC MEDIUM AT A TEMPERATURE OF 60-100*C. AND SUBSEQUENTLY ISOLATINGTHE TARGET PRODUCT. THE HEREIN-PROPOSED COMPOUNDS CAN FIND APPLICATION AS ELECTRON-EXCHANGE COMPLEX-FORMING MATERIALS IN CHEMICAL INDUSTRY, METALLURGY, AND IN OTHER INDUSTRIES.
