Hello we are trying to prepare a solvent based solution of different kinds of minerals which can be added to reverse osmosis permeate water so that some of the essential minerals can be added back to the water. Do anyone knows which solvent we should use?
I think water is the best solvent, assuming you want to remineralise the RO water for drinking it. Your solution might become a slurry depending on the required volume. Have you considered simply using a solid mix of these minerals? A solid mix would allow for a more homogeneous mix of different minerals than a low volume liquid.
