Abstract
The chelating resins, which were loaded some kinds of metal ions to the ends of the functional groups, have specific functions as selective adsorption, catalyst and etc. It is possible to remove many sorts of ions (For instance; fluorine, selenium and arsenic ions) from waste water, which aren't easily treated by usual methods.
In this paper, we present applications of waste water treatment with these metal salt type chelating resins. The aluminum type chelating resins with aluminum amino-methylphoshate salt groups selectively adsorb and remove fluorine ions from waste water. Also, the iron type chelating resins with iron iminodiacetate salt groups and these chelating resins treated with NaOH solution possess high selective adsorptions to selenium and arsenic ions from salt aqueous solution, respectively.
