dc.description.abstractActivated carbon is used in the mining industry for the recovery of precious metals, and is used in the treatment of waste-waters for the removal of pollutants. During such applications the carbon becomes poisoned by a wide spectrum of organics of which the concentrations and identities are not usually known. A simple mass balance and TGA data can be used to calculate the loading of organics on activated carbon if the residual mass of pyrolysed organics is known; however, this information is not usually known for industrial carbons. In such cases the slope of the TGA curve for the loaded carbon heated above 850 °C in an inert atmosphere may be used to estimate the loading of organics on the carbon. Different carbons loaded with phenol, benzoic acid and methylene blue, as well as carbons loaded from plant solutions, were used to verify the use of this new procedure. © 1987.
