DETERMINATION OF RARE-EARTH ELEMENTS IN A CERTIFIED ROAD DUST SAMPLE (BCR-723) BY INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY
Abstract
We have proposed two methods for determining
rare-earth elements (REEs) in road dust by ionizing the
sample with inductively coupled plasma and then using mass
spectrometry (ICP-MS) to separate and quantify the ions. The
first method is based on dry ashing of samples in a muffle furnace
followed by processing of the remainder with a mixture
of hydrochloric and hydrofluoric acids. The second method
involves the decomposition under microwave heating with
the following sequential processing by fluoroboric and nitric
acids. Both techniques employ sorption separation of REEs
from the solutions on activated BAU carbon, modified by a
mandelic acid, and subsequent desorption of 3% nitric acid.
We present new data on the content of rare-earth elements in
standard samples of road dust, BCR-723, obtained with the
use of the developed techniques.
