スギ，ヒノキ樹皮及び樹皮—透水性ポリマー複合材料の重金属イオン吸着能評価

The radioactive pollutions in environment caused by the accident of atomic power plants in Fukushima, Japan, is still serious and rapid measures to the severe problem is required. It is well known that various biomass have adsorption ability for toxic metal ions from aqueous media. We have evaluated the adsorption ability of the bark of Cryptomeria japonica and Chamaecyparis obtusa, and their hybrid materials with hydrophilic polymers, for cesium, strontium, and other heavy metal ions. As the results, these materials are useful as adsorbents for a water and soil purification system.
