説明

Vanadium concentration in 105 bottles of various commercial mineral waters was measured by inductively coupled plasma mass spectrometry (ICP-MS). (1) The calibration curve of vanadium concentration obtained by ICP-MS showed a good linearity. (2) The chloride (Cl-) affecting the measurement of vanadium concentration did not affect the recovery rate of vanadium up to 100 ppm when Cl-was added as NaCl. (3) The average vanadium concentration in all the commercial mineral waters was 0.013mg/l, whereas the average vanadium concentration in groundwater from the foot of Mt. Fuji was 0.059mg/l. Forty-five percent of the mineral waters showed a vanadium concentration below 0.001mg/l. (4) One of the imported bottles of commercial mineral waters showed the same vanadium concentration as groundwater around Mt. Fuji.
