FIELD : chemistry.SUBSTANCE : invention relates to sorption technologies, in particular to adsorbents, which are applied for drying from water of gaseous media. Adsorbent for removal of water from gases contains porous matrix, into pores of which active water-absorbing hygroscopic substance from the group of halogenides of alkaline earth metals is introduced, and as porous matrix applied are mesoporous silicates from the group including silicate MCM-41, alumosilicate, zirconesilicate or titaniumsilicate, obtained by method of sol-gel method or template synthesis with the following heating in air flow at temperature 200-450°C for 1-4 h, with water-free calcium chloride in amount 40-100 wt % counted per dry substance of matrix being introduced from water solution into mesopores with size 2-10 nm and the total volume of pores over 1 cm/g by method of impregnation and the following drying of adsorbent in air at 100°C for 2 h.EFFECT : invention ensures creation of effective adsorbent with high capacity by water.
