Gelation and characterization of alginate microspheres mixed with other polymers are well described previously in the literature (7,2). However, no references for the interaction of emulsan and other polymers were found. Comparative optical microscopy of alginate and emulsan-alginate microspheres showed different surface morphologies (Figure 3). The results were confirmed by SEM (Figure 4).

Just like activated carbons and hydrous oxides, potentiometric titration can be used to characterize the acid-base surface properties of the resins (4—8,12,15-19). The ionization reactions and the constants (pK values) can be determined according to the titration data. For example, Chen and co-workers reported a successful case of characterization of a cation resin—a calcium alginate based ion exchange resin (CABIER) (17). The study included three steps ...
