Abstract
The authors have been investigating harmful-heavy-metal adsorption property of several gels aiming at utilizing as environmental purification materials. In our previous investigations, their hazardous-heavy-metal capturing capability was revealed with an advantage in the large (captured ions / absorbent material) weight ratio. In the present study, it has been demonstrated that the terminal group substitution in a heavy-metal-anion capturing gel has a dominant effect on its efficiency.
