Description
Summary:A method for the detection of trace As(III), As(V), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA) in groundwater by capillary electrophoresis-inductively coupled plasma mass spectrometry(CE-ICP-MS) was developed. The results showed that the above four species of arsenic were baseline separated within 9 min under the optimized conditions. The detection limits (S/N = 3) of As(III), As(III), DMA, MMA were 0.2-0.5 [mu]g/L, and the RSD (n=6) of the peak areas were smaller than 4.0%. The recoveries were 93%-106%. The result indicated that As(III) and As(V) as the main arsenic speciation existed in the groundwater of Inner Mongolia.
