| Resumen |
Evaluation of the feasibility to use charcoal impregnated with triethylenediamine (TEDA) as a sorbent in respirator cartridges or high-volume air-cleaning adsorbers for trapping organic forms of radioiodine in air. Desorption rates of TEDA from impregnated charcoal samples (5% TEDA) were measured from 70 to 100°C. The highest rate extrapolated to 25°C was only 0.12mg/m3, well below the vapour pressure of TEDA (3500mg/m3) and the exposure limit for similar amines (4-40mg/m3). Effects of varying flowrate, bed depth, humidity and increasing the TEDA molecular weight were examined. TEDA-impregnated charcoal could be safe to use only at low temperature and air flow rates. |
