- Self-introduction
- I belong to the Chemical Engineering Program and am studying polymer gels. My previous job was a petrochemical plant engineer. When I was a student, I was researching immobilized culture of animal cells in polymer gels. Polymer gel is a substance that has both liquid and solid properties, and its unique properties can be applied to various fields such as reaction, separation, storage, and energy conversion. Although the polymer gels are studied in all over the world, only simple properties such as water absorption and water retention have been utilized industrially. Therefore, I am researching the utilization of the unique physical and chemical properties of polymer gels such as environmental purification and substance production methods.

- Selective Metal Ion Recovery from Waste Water by Using Hydrogel with Tertiary Amino Group, Takehiko. Gotoh, Masahide Sano, Asuka, Ogawa and Satoshi Nakai, IWA-ASPIRE Conference 2017, Without Invitation, English, International Water Association, Kuala Lumpur, New metal ion recovery method with hydrogels as a reaction and separation media has been investigated. Hydrogels based on copolymers of 2-(Dimethylamino)ethyl methacrylate, N-3-(Dimethylamino)propyl acrylamide and N,N-dimethylacrylamide were prepared. Diethyleneglycol dimethacrylate was used as a crosslinker. The hydrogel with tertiary amino group exhibited high pH value inside of them when they swelled in water because the tertiary amino group was protonated by water and produced hydroxide ion was retained in the hydrogel. When the hydrogel was immersed in the metal ion aqueous solution, the metal ion diffused into the hydrogels to produce metal hydroxide in the hydrogel. The metal hydroxide within hydrogel was easily separated from the solution. The recovery amount of the metal in the hydrogel was increased with the concentration of the metal ions in the solution. The pH value of the hydrogel could be controlled by the concentration monomers at the preparation. The selective recovery of a certain metal ion from the mixed metal ion solution was attained by controlling the pH value of the hydrogel. The results obtained here suggest the possibilities of the novel metal ion recovery method replacing the coagulation and/or adsorption methods.
