Abstract

PROMISING DESENSITIZING TREATMENTS DEVELOPED BY PHASE I RESEARCH WILL BE OPTIMIZED AS TO REACTION CONDITIONS. ASC WHETLERITE AND BPL CARBON WILL BE COMPARED BY SORPTION-BED EXPERIMENTS, IN TREATED AND UNTREATED FORM AND AT HUMID AND DRY CONDITIONS; TESTS WILL INCLUDE PARAMETERS AND CONDITIONS REFLECTING ACTUAL GAS-MASK CANISTER PERFORMANCE. IN ADDITION TO TESTS WITH SORPTION BEDS, MICROBALANCE EXPERIMENTS WILL MEASURE ADSORPTION KINETICS AND ISOTHERMS. SORBATES WILL INCLUDE A LOW MOLECULAR WEIGHT HYDROCARBON OF HIGH VAPOR PRESSURE, A WATER-SOLUBLE ALCOHOL AND, SPECIFICALLY, HCN AND COCL(2). SPECTROSCOPY AND ELECTRON MICROSCOPY WILL EXPLORE THE FUNDAMENTALS OF THE EFFECTS OF THE TREATMENTS ON THE SORPTION PROCESS.
