Spike recovery and detection limit. Species of arsenic found in drinking water include AsO32 3 (arsenite), AsO32 4 (arsenate), (CH3)2AsO2 2 (dimethylarsinate), and (CH3)AsO22 3 (methylarsonate). Pure water containing no arsenic was spiked with 0.40 mg arsenate/L. Seven replicate determinations gave 0.39, 0.40, 0.38, 0.41, 0.36, 0.35, and 0.39 mg/L.15 Find the mean percent recovery of the spike and the concentration detection limit (mg/L).
