Substitution influence of halo polyurethane foam on the removal of bismuth, cobalt, iron and molybdenum ions from environmental samples
文摘
The polarity of PUF was modified by attaching halogen atoms to the surface. The sorption performances were investigated by batch and column experiments. X-PUFs possess highest sorption capacity for Bi, Co, Fe and Mo ions than PUF. The processes of metal extraction/recovery using X-PUFs are very fast. X-PUF could be successfully regenerated and reused.
