Determination of iron and aluminium in Tamm's soil extracts

Abstract

Two rapid methods, atomic absorption spectrophotometric and Ferron colorimetric, are described for the determination of iron and aluminium in Tamm's oxalate soil extracts. The former is accurate for the wide variety of soils tested and the latter is also accurate for these soils except where the content of nickel, copper, or zinc is abnormally high. © Taylor & Francis Group, LLC.
