His innovative methods have implications for various industries, including electronics and materials engineering.

Latest Patents

Ishibashi holds a patent for a novel method that enables the selective separation and concentration of gallium and/or indium from solutions containing them in very low concentrations alongside other metal ions. The method involves passing the solution through a bed of chelating ion exchange resin with an amino carboxylic acid group, either immediately or after adjusting the pH. The gallium and/or indium adsorbed on the resin is then desorbed using a mineral acid. After pH adjustment, the eluate is passed through another bed of chelating ion exchange resin to recover gallium and/or indium in a concentrated solution. This innovative approach has the potential to enhance the efficiency of metal recovery processes.
