WebThis equation can approximate the sigmoidal shape often observed in binary isotherms (exchangeable cations are relatively preferred when they occupy a small fraction of the exchange sites, cf. Bloom and Mansell, 2001; Bond, 1995). The Gapon convention expresses exchange per mol of exchange sites, rather than per mol of exchanging ion:
