Important relationships predicted by the model:

• Linear relation between inverse surface conc. and

inverse solution conc., i.e.

1/surface conc.[?SOM] ~ 1/solution conc. [M+]

• when K[M+] << [H+] , linear ?SiOM ~ [M+] /[H+]

• when K[M+] >> [H+] , ?SiOM ~ ?0 saturation of surface sites,

independent of [M+]
