Method of extraction of arsenic from water solution |
| abstract |
FIELD: metallurgy. n SUBSTANCE: for immersion of As from diluted solution it is used the sediment of nanocrystals of akaganeite β-Fe 3+ O(OH) in nanostructured range in the limits from 2.12 to 2.34 nm, under ionic strength of solution 0.1 М KNO 3 and рН 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 мг As(V) to gram of akaganeite is generated by immersion of iron chlorides (III) ammonium carbonate, with osmose on diaphragm М 45 and sublimation drying under the room temperature. n EFFECT: diminution of costs and exceeding the efficiency of water solution of sewage from cation of heavy metals and anions. n 3 cl, 3 tbl |
