The present work investigated the static absorption of metallic mercury vapor in some compositions of collecting protective polymeric coatings (CPPC) which contain polyvinyl alcohol or a polyvinyl acetate emulsion as the film-forming base. In the applied aspect, the statement of the problem has meaning in connection with the high toxicity of mercury vapor and the need to search for effective methods of purifying the air in sites associated with the manufacture and use of metallic mercury, especially radioactive isotopes of mercury in radiochemical laboratories. Experimental results indicated that the most effective composition of a coating intended for the absorption and strong retention of atomic mercury should combine an adequate concentration of a chemically active sorbent (MnO/sub 2/, for example) with a loose, open structure of the polymeric film. The search for an optimum recipe should apparently be conducted with a view to choosing appropriate surface-active additives and gel formers. The use of pore- or foam-forming agents with the objective of increasing the working surface may also prove very effective.
