I am looking for an Ion Exchange Resin for anionic monovalent ions.
I would like to replace chlorides with bicarbonates for drinking water purpose.
Which resin could be suitable for this experiment?
Category: Academic
Proceeds with strong anions resin with integrated molecular links of calcium or magnestype..

Where is this project for? In many countries the choice of resin for a potable application would be limited to those that were on approved lists. There may be others that are perfectly suitable but the manufacturers may not have submitted them for approval because of the costs of the process against the likely returns for an infrequent application.
I am actually doubtful that there is a resin available that is suited to your application

Thank you Steve. What kind of countries are these? This is a theoretical research with no target yet. I live in Argentina. Where could I find these lists? Thanks again

The regulatory agency for each country will maintain an approved list. In the UK this is kept by the DWI (Drinking Water Inspectorate). Sorry I have no idea about Argentina. Have you thought about weakly basic anion resin and hydroxide ?neutralisation?

I use MgO (Magnesium Oxide) prill beads to purify drinking water.
The prill beads come from a deep mine in Nevada. They are processed at 700 degrees which turns them into ceramic beads that do not dissolve in water.
The beads place a positive charge in the water that shatters the magnetic bond that holds together any contaminants or pollutants (chlorine, fluoride, heavy metals: zinc, copper, lead, chromium-VI, pesticides, radiation, pharmaceuticals, mold, Ecoli, bacterias, etc) and gasses them out of the water. It raises the water pH to 8.7, high alkalinity, high oxygen, and thins the water so that can penetrate the cell membranes and flush out your toxins.
As to hydration: 3 glasses of prill water is equal to drinking 1 gallon of reverse osmosis water.
Great for acid conditions: acid-reflux, heartburn and acne.
Great for ice cubes.
Google "prill water uses".
Please tell others about us cuz that is how we grow.

Richard, If this material puts positive charge in the water, how does it remove all contaminants? With Ion Exchange, we exchange positive ion like Cu++ with 2 ions of H+. Can you explain the chemistry of what is happening with ions in the water?

I don't understand any of this except the pH. Can you explain with data?

Use any strong base anion resin in the bicarbonate form. Regenerate with sodium bicarbonate.

Thank you! Do you think DOWEX Marathon A2 could work?

Why do you want to remove the chloride? Is the water saline or high TDS? Of course that change would likely have a significant effect on the distributed water stability, corrosion, pH, indices, and interaction with pipes and biofilms. Suggest first piloting in simulated or isolated systems.

Calcium chloride hydrolyzes on the acid side, bicarbonate is basic. You could be heading for trouble.

I have excess of Chloride because I previously dosed Ca2+ with CaCl2. But the main goal is to dose bicarbonate.

Purolite Anion Resin is suitable

Thank you. I will check on it
