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.
