Procedure for obtaining dissolved salts and acids from other disposables, with ion exchange resins, which is done in two steps, by placing the resin exchange in columns. In the first stage, the resin is charged with the cation which corresponds to the salt that is desirable for taking, by dissolving a suitable salt through the resin. The charge thus charged is extracted in a circular manner from the column at the same time during which it is replaced by regenerated resin, which results from the second stage of processing. Before passing the used resin in the first step to the second step, it is released from the saline solution with which it was charged by draining and washing with water, or by displacement with another solution. In the second stage of treatment, the resin is regenerated as having passed through the same dissolution of salt or acid whose anion is the one that corresponds to the salt which is desirable for taking. |
