Zusammenfassung:FIELD: metallurgy. ^ SUBSTANCE: for immersion of As from diluted solution it is used the sediment of nanocrystals of akaganeite beta-Fe3+O(OH) in nanostructured range in the limits from 2.12 to 2.34 nm, under ionic strength of solution 0.1 KNO3 and 4.5. The immersion of arsenates is done under the ratio of akaganeite of iron (Fe/As) to anion of arsenic equal to 10/1. The sediment of akaganeite with surface area 299-300 m/g and maximum of sorbite capacity 100-120 As(V) to gram of akaganeite is generated by immersion of iron chlorides (III) ammonium carbonate, with osmose on diaphragm 45 and sublimation drying under the room temperature. ^ EFFECT: diminution of costs and exceeding the efficiency of water solution of sewage from cation of heavy metals and anions. ^ 3 cl, 3 tbl
