摘要：

Molybdenum (0-2.5 mug) may be determined spectrophotometrically at 385 nm after flow-injection extraction into chloroform of the chelate of molybdenum(VI) with quinolin-8-ol. The carrier stream was dilute sulphuric acid, pH 0.85. The injection rate was 20 h-1. The calibration graph is linear up to 10 mug ml-1 Mo and the detection limit is 0.11 mug ml-1 based on injection volumes of 250 mul. The system has been applied to the determination of molybdenum in low alloy and mild steels.
