Abstract :
Soils contain many kinds of inorganic and organic particles, nanoparticles. In addition, natural nanoparticles could strongly influence on solubility, transport, degradation and bioavailability of environmental pollution. The present article deals with the extraction and characterization of nanoparticles in soil. Nanoparticles were extracted from 5 soil samples in different regions of Ulaanbaatar city. The suspension of soil was prepared by a sonication and centrifugal method. Size distribution of nanoparticles was measured by using the Photon Cross Correlation Spectroscopy (PCCS). The results showed that, size distriburion interval of soil samples are 319-708 nm, 343-659 nm, 276-659 nm, 570-1094 nm and 319-612 nm respectively. On the other hand, there is not determined ultrafine nanoparticles. This result demonstrates that soil contamination and degradation of Ulaanbaatar city could be less.
