Method for the removal of heavy metal ions from contaminated water and a suitable therefor porous membrane

摘要

it is a procedure for the simultaneous removal of many different schwermetallionen from contaminated water is described.many different schwermetallionen can simultaneously and effectively removed by the filtration of contaminated water through a porous membrane, a porous membranartige, harzmatrix and many side chains, which contains chemically to both surfaces and the surfaces d he porenwu00e4nde matrix are linked with each seitengruppe a chelatgruppe,preferably a iminodiessigsu00e4uregruppe,, and by the end of the filtration when the concentration of the filtrate schwermetallions determinants, a predetermined value is reached. after the erfindungsgemu00e4u00dfen process many different schwermetallionen, e.g. kobaltionen and nickelionen effectively from contaminated water, e.g.water for power plants or waste water from nuclear power plants, at the same time, and efficiently on a commercial scale to be removed.
