REMOVAL OF NERVE GAS GB FROM WATER UNDER COLD-WEATHER CONDITIONS

摘要

Nerve gas GB can be effectively inactivated in water at moderate or warm temperatures by means of alkali hydroysis. The required dosage is 1 1b of soda ash or calcium hydroxide per 1000 gal of water.nNerve gas GB can be effectively inactivated in cold water by means of superchlorination with high-test calcium hypochlorite. The required dosage is 1.2 1b per 1000 gal of water. After inactivation of the GB, the hypochlorite ion is removed by treatment with activated carbon. The required dosage of carbon is 5 1b per 1000 gal.nWater decontaminated by either of the above procedures can be effectively treated with the Corps of Engineers Mobile Water Purification Unit yielding an effluent water that is non-toxic, potable, and palatable.
