Carbon tetrachloride detoxification

Szutowski MM. 1975. Effect of carbon tetrachloride on activation and detoxification of organophosphorus insecticides in the rat. Toxicol Appl Pharmacol 33 350-355. 

For detoxification of carbon tetrachloride (CCI4), e.g. in groundwater, de-chlorination is necessary. Iron metal, Fe", is commonly used for this purpose. 

Halide-saturated hydrocarbons such as carbon tetrachloride degrade very slowly, if at all, when exposed to solar detoxification treatment. Bicarbonate, a common constituent of groundwater, acts as a scavenger of hydroxyl radicals and can significantly hinder solar detoxification treatment. The presence of nontargeted contaminants in process infiuent can lower process efficiency. 

Many nonpolar molecules (e.g., methane and ethane) are biologically inert and require no detoxification. But, if a nonpolar molecule is biologically active (e.g., benzene and carbon tetrachloride), it is not easily detoxified (Reeves, 1981).
