How can ion exchange resin be activated?
Cation exchange resin can be activated in vivo. The liquid amount of 2 times the volume of resin. The activation solution with a concentration of 3.0MOL/L hydrochloride, through the resin layer at a flow rate of 1.2-4.0M/H, the volume of 1-2 times, the volume of the resin concentration of 2.0-2.5MOL/L sulfuric acid soaking more than 3H
The anion exchange resin can be activated in vitro. The amount of activating liquid is 1-2 times of the volume of resin. The preparation of 2.0-2.5MOL/L activation with sulfuric acid concentration on the content of Sodium Bisulfite, Sodium Bisulfite gel type strong basic anion exchange resin 45G/L, the macroporous weak basic anion resin for 28G/L activation, the resin in the activation solution overnight
The method is applicable to the activation of anion and cation exchange resin in the treatment of chrome plating wastewater by ion exchange
