Abstract
Methods were developed for the trace determination of total arsenic, `As(III)ʹ, `As(V)ʹ, dimethylarsonic acid (DMAA) and monomethylarsonic acid (MMAA) in sea and hot-spring waters by hydride generation/trapping and atomization in a graphite furnace using coated graphite tubes. Selective medium reactions were used to generate selectively hydrides of each arsenic species:
