Abstract
An automated method for the determination of arsenic acid (AsV), arsen ous acid (AsIII), monomethylarsonic acid (MMAA) and dimethylarsinic ac id (DMAA) was developed using a commercial available flow injection hy dride generation system. By carrying out the hydride generation in sel ected acid media the determination of As(III) alone, of MMAA and DMAA by sum and by different sensitivities, and of all four species is poss ible.
