In Reply:-We agree completely with Dr. Woehlck that the small amount of carbon monoxide formation observed after Baralyme rehydration was probably a result of incomplete mixing of the added water with the absorbent granules. In the technical range of pouring, dribbling, sprinkling, and misting, we dribbled the water. Presumably sprinkling or misting, with better mixing, would have more completely rehydrated the absorbent. Similarly, use of excess water would likely provide greater rehydration.
Before “taking the plunge,” however, we suggest evaluating the effect of such measures on the scavenging characteristics of carbon dioxide absorbents.
