ACCORDING TO THE INVENTION, THE PROCESS CONSISTS OF TWO STEPS, THE RESIN BEING PROVIDED IN TWO COLUMNS. IN THE FIRST STEP, THE RESIN LOADS WITH THE CATION CORRESPONDING TO THE SALT TO BE OBTAINED BY PASSING A SOLUTION IN THE RESIN. THE LOADED RESIN IS CYCLICALLY EXTRACTED FROM THE COLUMN AS IT IS REPLACED FROM THE REGENERATED RESIN TO PROCEED TO THE SECOND STEP. THE RESIN IS WASHED OR MOVED WITH ANOTHER SOLUTION BEFORE ENTERING THE SECOND COLUMN. IN THE SECOND STEP, THE RESIN IS REGENERATED BY IMMERSION BY A SECOND SOLUTION OF WHICH THE ANION CORRESPONDS TO THE SALT THAT ONE WANTS TO OBTAIN. |
