Water purification, e.g. precipitation of heavy metals, involves using iron and/or sulfide-containing pyrolisates of organic materials optionally in powdered admixture with bentonites and/or oxidic iron and/or manganese compounds

摘要

Particulate Fe- and/or sulfide-containing pyrolisates of organic materials optionally in powdered admixture with bentonites and/or oxidic Fe and/or Mn compounds are used in water purification.
