Uses:
(1) used for the extraction of rare metals:
A tertiary amine as the amine-based ion complexation extraction: tri-n-octylamine (TOA) in a hydrochloric acid solution, separation of cobalt, nickel, extraction uranium; trialkyl tertiary amine (N-235, 7301) in a hydrochloric acid solution, separation of cobalt, nickel, . Extractant lower price, is also gradually massive for gold, copper and other metal extraction process to expand the range of applications.
(2) the treatment of industrial wastewater extractant complex extraction method:
Industrial wastewater containing phenolic pesticides, paints, pharmaceuticals, photographic materials, organic synthesis industry wastewater, recycled wastewater phenolic complex extraction method is commonly used in industry. Recently, more processing tertiary amine extractant containing organic acids, esters and other industrial waste water is better, and vigorously promote use.
