Abstract

A system of progressive leaching of soil samples was developed by which it is possible to locate the distribution of metals over the various soil phases. The sequence includes a new method of reduction of iron oxides by hydrazine chloride, which is described in detail. The system enables one to determine on a single 2-g sample the elemental concentrations in the following phases: water-extractable, ion-exchangeable, reducible Mn, organic material, reducible Fe, clay and residue.

Application of the sequential analysis to eight Tasmanian soil profiles indicates a much stronger scavenging effect by iron oxides than is generally recognized. The quantitative expression of the scavenging effects aids in discriminating between true and false "anomalies". No geochemical soil sampling programmes should be undertaken without analysis of manganese and iron oxide fractions.
