二三のポリビニルアルコール誘導体のHg^2+,Cd^2+吸着能
To obtain polymers able to capture heavy metal ions like Hg^ or Cd^ in water, functional groups having affinity for such metal ions were introduced in polyvinyl alcohol chain. Thiol group and -NH (RCOOH) group were selected as such functional groups. Several methods were carried out for introduction...
