Objective:
To establish a method for determination of disulfiram in the workplace atmosphere by liquid chromatography.
Methods:
Sampling with glass fiber filter, eluting with methanol, separating with C18 column, and determination with liquid chromatography.
Results:
The bearing capacity of glass fiber filter exceeded 3.45 mg per piece. The elution efficiency was 97.8%∼101.0% The relative standard deviation varied from 1.09% to 1.44%. The limit of detection was 0.1 µg/ml. The minimum detectable concentration was 0.011 mg/m³ (with sampled air volume of 45 L).
Conclusion:
The method has high selectivity, accuracy, and precision and strong applicability.
