Abstract:

The mechanism of water soluble polymer complexing ultrafiltration for removing heavy metals is analyzed,and the influencing factors in the separation process,such as pH,concentration ratio of metal ions and polymer,and added salt are summarized.In addition,the research progress in the technology of selective separation and that of polymer regeneration by acidification and electrolysis are reviewed.At the end,the membrane fouling problem,which is the restrictive factor hindering the industrialization of this technology,is emphatically overviewed,and the developing foreground is predicted.

Key words: water soluble polymer, ultrafiltration, selective separation, membrane fouling
