Applications of X-ray absorption fine structure spectroscopy to soils

Published

Journal Article

Physical and chemical aspects of X-ray absorption fine structure spectroscopy (XAFS) and its application in soils are discussed. This technique can determine the local chemical and structural surroundings of a particular elemental species in soil and water or other natural systems, without the need to subject the sample to a foreign atmosphere. Electronic information and a fingerprint of the X-ray absorbing element's local environment is provided and can be used to determine the speciation of an element in media like soils. Precise structural information (e.g. bond distances within 0.02 Å can also be ascertained with this method, although this precision is often difficult to obtain in heterogeneous materials. Nevertheless, XAFS is a method that can contribute significantly to our knowledge of soils and soil reactions. -from Authors
