英文摘要: Abstract(#br)A simultaneous analytical method for six arsenic species was established using high performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). Arsenate (iAs V ), arsenite (iAs III ), monomethylarsonic acid (MMA V ), dimethylarsinic acid (DMA V ), dimethyldithioarsinic acid (DMDTA V ), and dimethylmonothioarsinic acid (DMMTA V ) were separated with an isocratic elute. Additionally, DMDTA V and DMMTA V were synthesized by thiolation of DMA V and identified by electrospray ionization-mass spectrometry (ESI-MS). The developed method was based on a reversed phase C18 column and various eluents such as 50mM ammonium acetate, 15mM citric acid, 50mM formic acid, and 5.0mM...
