Sadaharu SHIIRAKO, Noriyuki MIYAZAKI, Shohei TANIGUCHI

Imino-di-acetate group was introduced onto a polyethylene film by radiation grafting method. The film grafted the chelate group to adsorb heavy metals was immersed into the extracts of two kinds of vitrification dusts and it’s adsorption-desorption properties was investigated .

The film adsorbed not only zinc and lead, the major heavy metals in the extracts, but minor elements such as molybdenum, silver, etc.. It may be possible to recover rare element resources from vitrification dusts.
