The physical and chemical characterization of a sulphur-impregnated active carbon, by combined adsorption and immersion techniques
A 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 sulphur decreases rapidly. It is also found that the impregnated carbon becomes hydrophilic but, in the case of SO2 adsorption, no change in adsorption capacity is detected.
