Determination of arsenic, selenium, and antimony by inductively coupled plasma mass spectrometry preceded by group sorption isolation

The conditions for group sorption isolation of As, Se, and Sb using new N,S-containing sorbents are described. It is shown that concentration in closed systems and use of microporous filters enable reduction of losses of As, Se, and Sb during the sorption process. Comparison of sorbents that differ...

Description
Summary:The conditions for group sorption isolation of As, Se, and Sb using new N,S-containing sorbents are described. It is shown that concentration in closed systems and use of microporous filters enable reduction of losses of As, Se, and Sb during the sorption process. Comparison of sorbents that differ in the number of functional groups does not detect any differences in sorptive characteristics. It is shown that the effect of the sorbent decomposition products on the determination of arsenic, selenium, and antimony by ICP-MS is insignificant and can be considered by correction of the reference experiment. The detection limits for As, Se, and Sb calculated by the 3S criterion are 0.06, 0.12, and 0.04 μg/L, respectively.
