Dvs isotherm
WebThe DVS plot for Form I ( Figure 2) shows that the sample takes up less than 1% w/w water at 84% RH. At 98% RH, there is a much larger water uptake (∼16%) that may be due to adsorption of water ... WebThe hysteresis between the adsorption isotherm and desorption isotherm is thought to be caused by the gradual desorption mechanism (percolation theory) due to the different size pores being combined. This percolation theory suggests that the pore size distribution obtained from the desorption isotherm is problematic to be used.
