Use of natural minerals as sorbents of radiocaesium in agricultural production

Abstract

The article elucidates the research of the efficiency of use of natural zeolite and bentonite sorbents and ferrocyanide containing sorbents: ferrocyanide-2 and FWV (ferrocyanide waste of viticulture) for treatment of multicomponent agricultural waste. It is established that all of the studied sorbents have a high sorption capacity regarding 137Cs from the aqueous solution and are characterized by relatively rapid absorption of 137Cs. 13CS is held the strongest by the sorbents ferrocyanide-2 and FWV. The efficiency of sorption of natural sorbents essentially depends more on the presence of K+ ions in the water solution and is less dependent on pH. The presence of potassium ions in the environment does not affect the effectiveness of sorption of ferrocine drugs. The high sorption capacity of ferrocyanide waste of viticulture (FVV) is established, which opens prospects for their practical application in agricultural production on the radioactively contaminated territories.
