Dynamics of oxygen sorption from water by copper-containing fibrous porous redox ion-exchangers
A most important field of practical application of oxidation-reduction (redox) polymers is the sorption of dissolved oxygen from water in order to prevent corrosion of power equipment. Copper-containing redox polymers, which have fairly high capacity and good swelling characteristics were used. Values of the dynamic exchange capacity (DEC) for copper ions, the redox capacity (ROC) for the reducing metal, and the dynamic reduction capacity for oxygen are given. It can be seen from these data that fibrous porous reactive materials (FPRM) in which the mass fiber content is 60% have somewhat better characteristics. The authors conclude that despite the fibrous porous material's considerably lower coefficient of internal diffusion, it is superior to granular EI-21 in the length of the masstransfer zone and in the coefficient of utilization of capacity, in consequence of the low linear density of the fibers. Their mass transfer zone is shorter by a factor of about 5.
