What Is The Identification Method Of Anion And Cation Exchange Resin In Softened Water Equipment?

Jul 22, 2020

Many customers have doubts, how to distinguish whether the ion exchange resin used in soft water treatment equipment is anion or cation? Today, I will briefly talk about the identification method of cation and anion exchange resin in soft water treatment equipment.

  The identification method of anion and cation exchange resin in water softening equipment is as follows:

   In the first step, take 2ml of the resin sample, place it in a 30ml test tube, and remove the water on the top of the resin layer by pouring.

   In the second step, add 5ml of 1ml/L HcL solution, shake for 1~2min, remove the upper solution, and repeat the operation 2~3 times. After operation, the cation resin is transformed into H type and the anion resin is transformed into cL type.

   The third step is to add pure water to wash, shake to remove the supernatant liquid, repeat the operation 2 to 3 times to remove excess hydrochloric acid.

   The fourth step is to add 5 mL of acidified 10% CuSO4 solution (containing 1% H2S04), shake for 1 min, and leave it for 5 min.

   After reading the introduction of the editor, I believe you have a relevant understanding of the identification method of anion and cation exchange resin in softened water equipment. If you want to know more, you can call the hotline or leave a message on the website, and we will contact you.
