A method by which harmful ions contained in water, such as copper, zinc, cadmium, chromium, and lead ions, are efficiently removed while generating a sludge in a reduced amount. The method is characterized by dispersing a hydrophilic high-molecular substance having anionic groups in the water to insolubilize the harmful ions with the hydrophilic high-molecular substance dispersed in an undissolved state. The remover for removing harmful ions is characterized by comprising a powder or fluid comprising a hydrophilic high- molecular substance having anionic groups.
Procédé permettant de supprimer efficacement des ions nocifs contenus dans l'eau, tels que des ions cuivre, zinc, cadmium, chrome et plomb, tout en générant une quantité limitée de boue. Ce procédé consiste à disperser une substance hydrophile à poids moléculaire élevé possédant des groupes anioniques dans l'eau afin de rendre insolubles les ions nocifs au moyen de cette substance hydrophile dispersée sans être dissoute. Agent servant à supprimer des ions nocifs et comprenant une poudre ou un liquide contenant une substance hydrophile à poids moléculaire élevé possédant des groupes anioniques.
