Dear Feras M. Kafiah,

firstable you should have an information on the Donnan equilibrium. The main two operating factors are the highest molecular weight and the degree of ionisation. This subject is more treated for the case of superabsorbers polymer gels. Regards

M. Ahasanur Rabbi

Degree of crosslinking and pH are two important factors that control the capacity of water absorption. Regards.
