As the concentration is low. You need flow through and not batch, then need to release the water again. So you would have to change the pH on a fast flow through, capture, release, then recorrect pH for release after. There is proteins that work well at low pH for selective REE capture, LanM as an example.

Interesting until you realize that most REE containing water sources which are viable are pH 3 and lower. So this method wouldnt work in vast majority of situations. There is tons of research on this and a very large DoD effort in this area far more economically viable than this currently. Cool work otherwise though...
