The effects of the diluent mixture's composition and crosslinking degree [divinylbenzene (DVB)] on the porous characteristics of the anion-exchange resins based on 2-vinylpyridine (2VP) and DVB, synthesized by suspension polymerization, in the presence of a diluent mixture constituted of heptane (HEP) and methyl ethyl ketone (MEK) at different proportions, were evaluated. The resins were characterized by mercury porosimetry, nitrogen adsorption (Brunauer-Emmett-Teller (BET) method surface area determination), apparent density, and swelling in methanol. The optical appearance of the copolymer beads was examined by optical microscopy. It was found that the development of porosity was attained whenever the content of methyl ethyl ketone in the diluent mixture was increased for all DVB contents employed.

In the present work, different kinds of porous copolymer networks based on 2-vinylpyridine (2VP) and divinylbenzene (DVB) containing anchored iodine were prepared and evaluated for inactivating Escherichia coli in an aqueous medium. By using bacterial viability assays with E. coli (AB 1157, wild-type), the iodine bactericidal effect was investigated at room temperature by elution through short columns filled with copolymer beads. Saline solutions containing bacterial cells at several contents (10 2 to 10 7 cells/ mL) were eluted. After each elution, cell content viability was determined by plating these suspensions on nutritive agar plates, incubating them at 37°C for 24 h, and counting as colony-forming units (CFUs). It was verified that the networks containing anchored iodine were completely bactericidal within a few minutes.
