Abstract
Method and apparatus for controlling metals in a liquid are described. The liquid is contacted with a hexahydrotriazine and/or a hemiaminal material, and metal is adsorbed from the liquid onto the material. The hexahydrotriazine and/or hemiaminal material may be made from a diamine and an aldehyde.
Claims10
A method comprising:
- exposing a liquid containing metal to a metal control material comprising a PHA or PHT material containing a plurality of aromatic bridging groups having the structure
- wherein L′ is a divalent linking group;
- adsorbing metal from the liquid onto the metal control material;
- and
- removing the metal from the liquid by separating the metal control material from the liquid.

A method, comprising:
- flowing a liquid containing metals through metal control material comprising a PHA material or a PHT material, wherein the PHA material or the PHT material is a reaction product of a diamine, having the general structure H2N—Ar-L′-Ar—N—H2, wherein Ar denotes a benzene ring group and L′ is a divalent linking group, and an aldehyde;
- and
- removing the metal control material from the liquid containing metals;
- and
- removing adsorbed metals from the metal control material by exposing the metal control material to a regeneration material.
