Unique ion pump made by scientists can revolutionize desalination, energy projects

Scientists from the University of California, Irvine, and Tel Aviv University have developed an innovative ion pump that allows ions to be moved in aqueous solutions without the use of chemical reagents. The technology could form the basis for more efficient water purification and desalination.

The development is based on an electrochemical system that controls the movement of ions using electrodes and switching electrical circuits. Ions are first accumulated on a porous electrode and then released into another solution. This creates a controlled and directed transport without the need for reagents or mechanical intervention.

In effect, the system operates like a “shuttle”: ions are gradually transferred between media under the influence of an electric field. This allows for precise control of the process and avoids unwanted side reactions, particularly electrolysis.

Key advantages of the technology include:

no chemical reagents and reduced environmental impact

controlled ion transport

high energy efficiency

stable operation without significant material wear

Unlike traditional methods, such as reverse osmosis or electrodialysis, the new approach does not require high pressure, membranes, or complex chemical treatment. Instead of filtration, the system actively moves ions, making the process more flexible and controllable.

The technology has a wide range of potential applications: from seawater desalination and wastewater treatment to the extraction of valuable elements and the creation of new energy systems. It also belongs to the promising field of nanofluidic solutions that mimic natural mechanisms of substance transport.
