Abstract A set of organoarsenicals were identified in aqueous phenylarsonic acid (PA) and o-arsanilic acid (AA) solutions treated with soil of volcanic origin in batch systems. The transformation products were separated by liquid chromatography (RP-LC) and identified with element selective inductively coupled plasma-mass spectrometry (ICP-MS) as well as molecular selective electrospray ionization-mass spectrometry (ESI-MS) detection after their HPLC separation. The identification of the main degradation products by means of ESI-MS, ESI-MS/MS and ESI-TOF-MS showed the occurrence of nitrophenylarsonic acid and methylphenylarsinic acid in the solutions containing AA and PA in contact with soils, respectively. Using irradiation of PA solution with visible light, new compounds related from PA appeared with increasing irradiation times which were identified as 4-hydroxyphenylarsonic acid, 3-hydroxyphenylarsonic acid and 2-hydroxyphenylarsonic acid. Additionally, a dihydroxyphenylarsonic compound was identified as impurity of PA.
