Summary
A proposed American Society for Testing and Materials (ASTM) method for the determination of arsenic and selenium content in coal has been used and evaluated in the Analytical Chemistry Laboratory (ACL) at Argonne National Laboratory (ANL) as part of an interlaboratory study. Coal is conducted with Eschka's mixture (MgO + Na2CO3), followed by determination of the arsenic and selenium content by hydride generation/atomic absorption spectrophotometry. The method was evaluated on a series of coals, including two National Bureau of Standards-Standards Reference Material (NBS-SRM) coals and twelve ASTM coal samples. Comparison of ACL/ANL arsenic and selenium data for the suite of coal analyzed showed excellent agreement with certified values for the NBS-SRM coals and with interlaboratory data from five other laboratories for the ASTM coals.
