Japan to develop new technologies using DNA recovery of rare earth

"Japanese Economic News" news, Hiroshima University and Aisin Seiki machine company Aisin COSMOS Research Institute recently co-developed a rare use of biological DNA extraction technology. The technology to salmon, trout and DNA adsorption rare earth metal into an acidic aqueous solution, recycling more than 90% purity neodymium, dysprosium.

High-tech components in the waste containing rare earth, neodymium, dysprosium and other confounding which must be separated neodymium, dysprosium, etc. can be recycled.

Study group contained in the discovery of DNA can be adsorbed phosphate group has the characteristics of rare earth metals, the experiment in the inner plastic tube filled with purified DNA cellulose, and mixed into the solution of various rare earth metal, and then into low concentration of hydrochloric acid, neodymium, dysprosium, cerium, etc. are successfully separated and recovered.
