The behaviour of Cr(VI) in soil under aerobic and anaerobic conditions
Abstract The method used in previous investigations to determine Cr(VI) in soil extracts was found to be unreliable and the behaviour of Cr(VI) in aerobic and anaerobic soils has beenExpand

The effects of aerobic and anaerobic incubation on the extractabilities of heavy metals in digested sewage sludge
Abstract Incubating digested sewage sludge causes wide variations in the solubilities of Cu, Ni, Zn, Pb, Cd and Cr in water, as well as in the reagents commonly used to assess availabilities of traceExpand

The effect of flooding and aeration on the mobility of certain trace elements in soils
The solution of some minor-element oxides by anaerobically decomposing plant material was reported by Ng S iew Kee and B l o o m f i e l d 14. In the presence of an antiseptic, water extracts of theExpand

The determination of iron(II) sulphide in soil in the presence of iron(III) oxide
Hydrogen sulphide is partially oxidised by iron(III) when soils containing sulphide and iron(III) oxide are acidified. Satisfactory recoveries of hydrogen sulphide are obtained by using a solution ofExpand
