Abstract
This communication is addressed to sorptive extraction of water from the atmosphere in arid areas. The method includes (a) sorption of water vapour in an adsorber in the night-time when the air relative humidity is comparatively high, and (b) desorption of the stored water and its subsequent collection in a condenser in the day-time. New materials adapted to this process are highly welcome. Composites “a salt inside a porous matrix” (CSPMs) have enhanced water sorption capacity and their properties may be intently varied in a wide range. In this communication, we make a preliminary analysis of CSPMs application for extraction of water from the atmosphere. Firstly, a general scheme of the water extraction is described. Then, we form a mental representation of an ideal solid sorbent that is optimal for the extraction of water from the atmosphere. Finally, we discuss how to design a real CSPM with properties meeting the formulated requirements, what are roles of the salt and the matrix, etc.
