Abstract
Identification of chemical elements in
polluted soil is very important because the soil can produce toxic substances
or become a medium for the growth of microorganisms. This research used the
LIBS (Laser Induced Breakdown Spectroscopy) method to detect chemical elements
in polluted soil. The emission spectrum is taken from pure soil and polluted
soil. Plasma emissions are then detected using a multichannel analyzer (OMA) to
obtain an emission line spectrum that represents the chemical element content
in the soil. The spectrum is compared with the standard reference spectrum of
atoms, ions, and molecules (National Institute of Standards and
Technology/NIST) so that the content of atoms and molecules in the sample can
be known. The research results found that there were heavy metal elements in
the form of Fe, Cu, and Mn in polluted soil.
