Application of the Scanning Electron Microscopy in Soil Fine-Dispersive Fraction Investigations
Keywords:soil, scanning electron microscopy, morphology.
This article presents methodological investigations of morphology and particles composition of fine-disperse fraction of the soils developed in moraine and glacial lacustrine deposits. The fine-disperse fraction from bulk soil was separated by a principle of peptization in distilled water according to Gorbunov’s method. Following the generally accepted strategy, the XRD method for determination of mineralogical composition of fine-disperse fraction has been used. The scanning electronic microscopes JEOL-35 was used to express mineral formation of separate particles or various their aggregations.
The investigations data obtained have shown substantial differences in morphology and particles composition of fine-disperse fraction of the different soil formation. These results are to be used in further investigations for modelling of heavy metals transport in soil.
