Ion exchange

  1. 1. ION EXCHANGE Anup Ghimire Rock Face Limited
  2. 2. The Process O It is a process of exchange of ions between the insoluble resin and the solution.
  3. 3. The Process O R-H + A+ < -- > R-A +H+ O R is the insoluble matrix of the ion exchange resin. O R-H is cation exchanger. O H+ replaces every A+ ions in the exchange process and electron neutrality is maintained.
  4. 4. Ion Exchange O Ion exchange is a natural process occurring in tissues of plants and animals, soils and minerals. O Assists to remove the cations and anions present in the water solution.
  5. 5. Applications O The treatment of radioactive and non-radioactive chemical species.
  6. 6. …applications O Softening, de alkalization, demineralization, nitrat e removal, condensate polishing. and pollution control.
  7. 7. Effect of Ions O Heating systems, steam generation and manufacturing process are affected by the presence particularly of ion concentration cations such in water as calcium, magnesium, sodium and potassium and anions such as sulphate, chloride, nitrate and silica.
  8. 8. Ion Exchangers O Strongly acidic O Strongly basic O Weakly acidic O Weakly basic
  9. 9. …Ion exchangers Naturally occurring and synthetic O Inorganic ion exchangers have greater selectivity and better disposal options than organic resin O organic ion exchangers are reliable and efficient in water coolant systems
  10. 10. …ion exchangers O Mineral compounds bentonite, Kaolinite Zeolites analcite, such and Illite and such chabazite, as sodalite as and clinoptilolite are naturally occurring inorganic ion exchangers.
  11. 11. …ion exchangers O Polysaccharides such as cellulose, algic acid, straw and peat, proteins such as casein, keratin carbonaceous and collagen materials such and as charcoals, liquites and coals are naturally occurring organic ion exchangers.
  12. 12. …ion exchangers O Zeolites, Titanates titanates, transition and silicometal hexacyanoferrates are inorganic synthetic ion exchangers.
