✦ Synopsis

commercially available active carbon, impregnated with sulphur, has been characterized and compared to the original carbon by using adsorption and immersion techniques. The specific reaction of liquid CS2 with sulphur, following the preadsorption of various amounts of n-nonane, shows that the accessibility of sutphur decreases rapidly. It is also found that the impregnated carbon becomes hydrophilic but, in the case of SO, adsorption, no change in adsorption capacity is detected.
