University of Tokyo Institute of Technology announced on the 28th, the research team developed the efficient absorption of radioactive cesium ions dissolved in water cloth. This fabric is expected to clear the Fukushima nuclear accident of soil and water with radioactive cesium contamination.

the Institute forced the research team led by Tian Chang-yi, a new technology will be able to absorb cesium blue pigment Prussian blue particles fixed to the cloth. 60 cm long, 40 cm wide, thin cloth made in this way, you can absorb 99% of 10 mg of cesium dissolved in 10 liters of water. If this cloth soaked with hydrochloric acid, is almost 100% recovery of cesium. This cloth is also expected for the purification of the sewage generated by the accumulation of rainwater tank rainwater or clean contaminated buildings.

researchers also consider the use of this cloth to remove the radioactive material in the soil: clay cleansed of radioactive cesium is easily absorbed in the first soil, then add the fertilizer solution was heated, the upper part appears clear solution containing radioactive cesium. Cloth dipped in the solution, to remove 70% of radioactive cesium from contaminated soil.

this research team is ready to improve the fabric of the absorption efficiency and uptake, and Fukushima University and other research institutions to continue to develop practical materials that can remove radioactive contamination. (Blue construction)
