Abstract
The analysis of arsenic in drinking water with ICP-USN method and ICP-VGA method
was studied. In USN method, wavelength of 193.696nm was used and in VGA method,
228.812nm was used. The values of arsenic of same sample in each method, MDL,
RPD, recovery, accuracy and precision were studied. The values of 14 sample of
drinking water were within 0.05ppm or were not detected. But in one sample high
value of 0.044ppm was detected. MDL of USN was 0.013ppm and MDL of VGA was
0.0004ppm. This results showed lower MDL of VGA but RPD of USN was better than
VGA. Recovery of two methods was same, but accuracy and precision of USN were
better than VGA. Therefore ICP-VGA method could be used according to this
result(MDL) when arsenic trace element detection in drinking water should be
achieved.
