Abstract
The adsorption properties of carbon-fiber busofite-type materials with respect to molecular iodine I2 and methyl iodide CH3I are investigated. It is shown that compared with SKT-3 activated carbon the efficiency of molecular iodine removal from air using busofite is 3 times higher and the efficiency for methyl iodide is 1.7 times higher. For busofite impregnated with 1–3 mass% KI, TEDA, or AgNO3 the efficiency of removal of CH3 131I (no carrier) increases by a factor of 2 and reaches 96–99.5% for 1–3 layers of busofite. The dynamical capacity of busofite with respect to CH3I is 8.5–10 mg/cm2 (∼250 mg/g), and the contact time on the first layer of the material is ≥0.08 sec.
