D113 resin is in a carboxylic acid on the pore structure of acrylic copolymer (-cooh) group - cation exchange resin.Mainly used in industrial water treatment, especially the removal of bicarbonate, carbonate and other alkaline salt, also can be used for zinc, nickel waste recycling, separation and purification of biochemical drugs, etc.
Anion and Cation Exchange Resin Pretreatment
The new resin to be used in the column is washed with hot water (clean tap water is also acceptable) repeatedly. The cation exchange resin can be heated at 70-80℃, while the heat resistance of the anion exchange resin is poor and can be heated at 50-60℃. water. When starting the immersion, change the water every 15 minutes, and stir it from time to time during the immersion. After changing the water 4-5 times, you can change the water every 30 minutes.
