Abstract:
1. A method of using a polymer to recover a metal, comprising: providing an insoluble polymer as shown in also known as “Poly 2” as follows, wherein R is H; R′, R″, and R′″, are one of the structures from the group of structures which include alkyl, alkenyl, alkynyl, and aryl structures; and n is the number of carbon atoms in a chain; providing metal ion primary solution with the Poly 2 and the metal ion primary solution having a ratio of Poly 2 to metal ion solution; providing the mixing of the Poly 2 with the metal ion solution by agitation to thereby form a secondary solution containing a metal ion Poly 2 complex; providing the filtration of the secondary solution with the filtration resulting in a third solution and a filter cake, the filter cake containing the metal ion and Poly 2 complex; providing the separation of the Poly 2 and the metal ion contained in the filter cake by heating the solid filter cake to a sufficient temperature to cause the Poly 2 to be converted into gas, leaving the metal for recovery.
