Notes On A Macro Porous Strong Base Anion Exchange Resin...

3.0 MATERIALS AND METHODS 3.1 Materials 3.1.2 DOWEX TAN 1 DOWEX TAN 1 is a macro porous strong base anion exchange resin with quaternary amine functionally designed for the removal of large natural organic compounds (NOM) from drinking water to reduce color and THM precursors. The resin was obtained from DOW chemicals. The resins are opaque white beads with particle size ranging from 0.3 to 1.2 mm and total exchange capacity is greater than 0.7meq/ml. 3.1.2 IRA-67 Weak base anion exchanger IRA67 was obtained from (company name)†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.... †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ 3.1.3 Chemicals, Glass wares and Plastic wares Table †¦.
