Аннотация

Sorbtion characteristics of magnetoplastic granules consisted of the fine-dispersed iron particles and magnetic hard ferrites in polyvinyl alcohol have been investigated. The possibility to control the time charac- teristics of sorbtion and desorbtion processes by means of magnetic fields was shown. Field with variable direction of the strength gradient decreases the time characteristics of sorbtion-desorbtion processes by factor of 7–10, and permanent field effect increases this time by factor of 1.3–2.5. It was also shown that use of sorbents in the composition of magnetic hard granules for methods of festering wounds treatment on the base of magnetofluidization in the variable fields increased the treatment efficiency by factor of 9.
