摘要:

Arsenic (III), arsenic (V), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA) were separated by ion-exchange chromatography. The elution sequence was as follows: 1.5 M ammonia followed by 0.12 M hydrochloric acid yielding As(III) 1 M hydrochloric acid followed by water yielding first As(V) and then MMA. Detection was by hydride generation-atomic absorption spectrometry. No interference was noted from 13 metallic ions.
