Adsorption Capacities of Hygroscopic Materials Based on NaCl-TiO₂ and NaCl-SiO₂ Core/Shell Particles

Figure 9

Water sorption analysis with isotherms at 25°C, 35°C, and 45°C: (a) and (d) for NaCl; (b) and (e) for NaCl-TiO₂; and (c) and (f) for NaCl-SiO₂, at relative pressure (0 to 1) top and an inset for low values of relative pressure (0 to 0.6) bottom. The isotherm of NaCl at 25°C shows a deviation obtained experimentally after the hygroscopic point and the correction as per the E-AIM model.
