Abstract: Objective To establish solvent desorption gas chromatographic method for determination of tert-butyl alcohol in the air of the workplace.Methods After tert-butyl alcohol in the air of the workplace collected with activated carbon tube and desorbed with 2％ 2-propanol in CS2,and then separated with DB-FFAP capillary column and detected with flame ionization detector.Results The linearity ranges were 0.6～2 264.0 mg/L.The limit of quantification was 0.6 mg/L.The determination has a good reproducibility.The intraassay and interassay precisions were 2.8％～3.2％ and 3.8％～5.7％.The desorption efficiencies were 93.9％～98.1％.Absorption efficiencies were 95.8％～100.0％.The breakthrough volume was above 7.1 mg in 100mg activated carbon.The samples in activated carbon tube could be stored for at least 14 days at ambient temperature.Conclusion The method is feasible for determination of tert-butyl alcohol in the air of the workplace.
