FIELD: process engineering.
SUBSTANCE: sorbent is made by mixing fine Portland cement 500 in flask with sodium chloride and water. Pellets are formed from said mix, heated at 105 degrees Centigrade and cured for three days at 20 to 40 degrees Centigrade. Cured pellets are damped in tap water to genitive reaction to chloride ions, dried to moisture content of 2%, held in 10%-solution of diethanolamine containing up to 1% of cetyl pyridine chloride, and dried to moisture content of 8%.
EFFECT: simple production of efficient sorbent.
