I want to calculate the ion exchange capacity of theoretically for polybezimidazolium polymer structure. Is there any equation has to use please specify.
Thanking you in advance for your valuable time.

The adsorption capacity is the maximum metal quantity uptaken by 1 g of resin.
Maybe you can find some information from the following link:

The Langmuir isotherm is a commonly used model to calculate the adsorption capacity of an adsorbate, as described by the following equation:
(Ce/qe)=(Ce/qmax)+(1/bqmax)
where qe (mg g - 1) is the amount of metal adsorbed per unit weight of the resin at equilibrium, Ce (mg L - 1) is the equilibrium metal ion concentration in an aqueous solution, qmax (mg g - 1) and b (L mg - 1) are the Langmuir constants related to the adsorption capacity and free energy or net enthalpy of adsorption, respectively. The relationship between Ce/qe versus Ce is linear, and the constants qmax and b are evaluated from the slope and intercept of the linear plot, respectively.
