Adsorption of bis(2-chloro-3-oxaperfluorobutyl) disulfide from nonaqueous solutions onto the surface of carbonyl iron particles was studied with the aim of modification of these particles. The adsorption parameters were calculated using the Langmuir equation from the adsorption isotherms obtained in the interval 20-60°C. With an increase in temperature and in the solvent affinity for the modifying agent, the limiting amounts of the reagent that has interacted with the iron particle surface increase. This fact suggests the chemisorption nature of the process. The products of the reaction of iron with the disulfide can be desorbed from the particle surface.
