Selective coordination of anions in water
« on: July 09, 2018, 02:43:53 PM »
Hey, this is my first post here.

I've been doing a lot of reading about anion coordination and was wondering if anyone here knows anything about it and can maybe share some articles.

The principle behind it I think is that anions can form complexes like chelated cations with certain functional groups. The functional groups usually are nitrogen containing groups like urea and seem to usually have a low solubility in water. A lot of the articles I've read so far talk about the potential applications in wastewater treatment but they usually end up doing extractions of the anions from water with mixtures of 1:1 Water:alcohol/dmso which isn't really practical for application.

The article below manages to do it without an organic solvent and so far is the fartherest along in application I can find. If I read it right it doesn't sound like it works outside a sodium brine but is still impressive.

Is this stuff developed enough for any reasonable application in the future or is it still just pipedream chemistry for now?
