title: Determination of thallium in soils by flow-injection-differential pulse anodic stripping voltammetry.
abstract: A relatively simple and quick method for the determination of thallium in soils is described. The method does not require any separation prior to determination. Total decomposition of the sample was performed in a teflon bomb. The interferences of iron, aluminum and manganese were removed by media exchange performed in a flow-injection measuring system, and the other interferences were removed by the use of the base electrolyte consisting of 0.15M EDTA and 0.1M ascorbic acid. The contents of thallium in the examined samples of soil were between 100 and 350 ppb.
