Equation, 1 uses sodium chloride (NaCl) as an example. These reactions are most complete when the pH of the effluent from either resin is nearer the neutral mark. Since the cation reaction produces an ,acidic, effluent and the anion is more of a neutralization reaction, the anion reaction is the more complete.

2/12/2014, · ,Ion, exchange (IX) is a reversible reaction in which a charged ,ion, in a solution is exchanged with a similarly charged ,ion, which is electrostatically attached to an immobile solid particle. The most common implementation of ,ion, exchange method in ,wastewater, treatment is for softening, where polyvalent cations (e.g., calcium and magnesium) are exchanged with sodium [ 36 ].
