(3) A method of adsorbing and removing heavy metal ions with an adsorbent; (4) A method of separating and removing heavy metal ions by membrane separation; (5) A method of extracting and removing heavy metal ions by solvent extraction; ( 6) A method of electrochemically depositing heavy metal ions on an electrode;
- the most widely used method (1) is to precipitate heavy metal ions as hydroxides, etc., but this method is difficult to post-process and recover generated sludge, and it is difficult to reuse treated water.
