METHOD FOR DETERMINING RHENIUM IN ORES AND ORE CONCENTRATES BY INVERSE VOLT-AMPERE MEASUREMENTS METHOD

摘要

FIELD: chemistry.;SUBSTANCE: rhenium is transferred to solution, it is accumulated on golden-graphite electrode in mixed solution during 90-120 sec with electrolysis potentials (-0.7 ÷--1.0) V relatively to chlorine-silver electrode at background 1M HCl with following recording of anode pikes in executive volt-ampere diagrams filming mode with speed of potential reaming 30-50 mV/sec and concentration is determined on basis of pike height in spectrum of potentials from 0.700 to 0.800 V by method of attested mixtures addition.;EFFECT: higher efficiency.;2 ex, 2 tbl, 1 dwg
