Magic-angle spinning deuterium NMR spectra have been used to evaluate the effects of activation to different extents of nutshell and coal-based carbon substrates on the adsorption of water (D 2 O). In general, separate signals are seen for water adsorbed in the micropores and in larger channels or at particle surfaces. The unactivated carbon shows negligible micropore adsorption except when...
A calorimetric method is described for the determination of adsorption and desorption of adsorptives that are liquid at room temperature, focussing on the sorption of water. Together with the isotherms, the sorption thermodynamics is determined in one experiment by determining the heat flow needed for generating the vapour and the heat flow generated by the adsorption process. An error analysis...
