I am performing some experiments and I'd need to buy a dialysis membrane (not a filtration membrane) that is not made of organic molecules. Teflon (C-F) would work, but haven't been able to find any online. Anyone knows whether dialysis membranes made of silica (or other inorganic materials) exist?
In case it helps: I plan on precipitating FeS minerals on top of the membrane (to use them for catalysis).
Probably , i am not Shure , polysulphone or polyamide could help your research . I say this , because many machines for water treatment are using these membranes .
There isn‘t a wide variety of materials available for membranes optimised for dialysis. They have to be cheap. Maybe diafiltration works for you as well. In that case you can choose teflon or a ceramic material.
