A sorbable substance (an Fe salt) is deposited on a porous support (activated C) by circulation of working solns. Through a stationary layer of C is performed dosed introduction of the sorbable substance with subsequent pptn. of Fe hydroxide by NH3, washing, drying, and calcination. To shorten the time of prepn., decrease the vol. of washing water, and increase the S capacity of the sorbent, the circulation occurs in stages; pptn. of Fe hydroxide and washing are performed with a space velocity of 300-600 h-1 for dosing of the sorbable substance in the circulating soln. at stages of deposition with velocity 1-1.5 mmol/h-g carrier.
