Abstract
PURPOSE: To rapidly and easily capture and remove heavy metals in waste water by capturing the heavy metals in the waste water through using polyamines having one dithioic acid residue or its salts in a molecule then adding iron ions.
CONSTITUTION: Polyamines having one dithioic acid residue or its salts in a molecule and ferrous ions or ferric ions are added to waste water to prevent the captured sludge from redissolving and to surely remove the heavy metals in the waste water. As paid dithioic acid residue or its salts in the molecule as a heavy metal capturing agent, there are dithiocarboxy ethylenediamine, dithiocarboxy diethylenetriamine or salts of Li, Na, K, Ca, etc., and the amounts of their addition are generally 1W3 times mole equiv. of the contents of the heavy metals, and the amount of addition of iron ions are suitably 1.2W3 times mole equiv. of the heavy metal capturing agent.
