Dynamic vapor sorption动态
WebDYNAMIC DEWPOINT ISOTHERM METHOD 237 yields a very useful assessment tool identified as the moisture sorption isotherm. A mois-ture sorption isotherm relates the amount of water sorbed (either adsorption or desorption) at equilibrium (or steady state) by a material at a given a w (or relative humidity, %RH) at a constant temperature.

WebThe adsorption and desorption performance of vesicular silica under static(for water vapor, n-hexane and 93# gasoline) and dynamic(for n-hexane) conditions were investigated with commercial silica gel(SG) and activated carbon(AC) as reference. The densities of surface hydroxyl group were determined by Boehm titration, which are linear to the ... Webchanges in relative humidity. Dynamic vapor sorption (DVS) analysis is a technique specifically designed to provide such information. EXPERIMENTAL . In a typical DVS experiment, the relative humidity (%RH) is stepped from a low initial level (either ambient or 0 %RH) to a high level (90-95 %RH), then back down to a
WebDynamic vapour sorption (DVS) is a gravimetric technique that measures how quickly and how much of a solvent is absorbed by a sample, such as a dry powder absorbing water. The water uptake describes how hygroscopic the compound is. Hygroscopicity is highly relevant in the evaluation of storage conditions and general stability, as “water ...
