摘要

Active carbons, grade 80CTC and active carbons impregnated with cobalt (II), chromium(VI), nickel(II) and cadmium(II) and copper(II) salts, etc were saturated with the vapours of thiodiglycol (TDG) at room temperature. The carbons exposed to TDG were subjected to thermogravimetric analysis (TGA). The thermograms indicated the reactions of metal salts with the adsorbate, and was confirmed by GC-MS after extracting the reaction products from TDG exposed carbon impregnated with chromium(VI) salt and sodium hydroxide. The extractants used were dichloromethane and methanol. 1,4-oxathiane4-oxide was the reaction product of thiodiglycol on Cr(VI) impregnated carbon.
