A graphite furnace atomic absorption spectrophotometer (AAS) was used to determine the arsenic (As) concentrations in drinking water. A large set of blank samples yielded an average blank signal of 0.013 and a blank standard deviation of 0.0030. The following data were obtained for a calibration curve. [As] (ppm) 2.0 4.0 6.0 8.0 10.0 Absorbance 0.17 0.28 0.48 0.53 0.72
