| 摘要 |
<p>The present invention is related to a method to extract out of water, concentrate and reformulate [18F] fluorides wherein:
- a dilute aqueous [18F] fluoride solution enters by an inlet (1) in a cavity (6) embodying an electrochemical cell with at least two electrodes (3, 4, 5) used either as a cathode or as an anode, passes through the cavity (6) and comes out of the cavity (6) by an outlet (2), an external voltage being applied to the electrodes, one electrode (4) being used as an extraction electrode, another one (3) being used for polarizing the solution;
- among the electrodes (3, 4, 5), at least one electrode (4) is in contact with and polarizes a large surface area conducting material (7);
- a flush of gas is possibly injected into the cavity (6) to purge the electrochemical cell and recover most of the remaining water therein, whilst keeping the extracted ions inside the electrochemical cell.</p> |
