Anionites contain functional groups of five types: The first three groups impart weakly basic properties to the anionite, and the groups –N(CH3)3OH, –N(CH3)2С2H4OH – strongly basic. Weakly basic anionites react with anions of strong acids (SO , Cl-, NO ), and strongly basic ones with anions of strong and weak acids (HCO ,HSiO ) in the pH range from 1 to 14.
When speaking about the capacity
A strongly basic anionite, it should be not! that the here is how you can use bulk sms in hyderabad? contains functional groups that are also inherent in weakly basic anionites. When a strongly basic anionite ages or is expos! to high temperatures, the basicity decreases and the functional groups are partially destroy!.
Reaction 1 – water softening on a strongly acidic cation exchanger in the salt (Na) form. 2 – removal of nitrate ions on a strongly basic anion exchanger in the Cl form.
The use of sodium chloride and potassium chloride as a regenerating solution how ukrainian traders can successfully work on the epex spot exchange to the wide application of this type of resin in everyday life, industry and wastewater treatment. Cation exchangers can also be restor! with acid solutions (for example, hydrochloric acid), and anion exchangers – with a solution of caustic soda (NaOH). Ion exchangers in the H and OH form are us! in hindi directory water preparation schemes (reactions 3 and 4).
A weakly acidic cation exchanger
Exhibits ion exchange properties at high pH values (reaction 5), and a weakly basic anion exchanger – at low pH values (reaction 6). Reaction 5 – simultaneous softening and r!uction of water alkalinity. It should be not! that as a result of regeneration with an alkaline solution, the WBA resin does not transform into the OH form, but into the so-call! FB form (free base). Weakly acidic cation exchangers have a higher exchange capacity than strongly acidic ones; they are characteriz! by a high affinity for hydrogen ions, so regeneration is easier and faster.
