Abstract:
Objective To establish a simultaneous determination method of cyclohexane,cyclohexanone and cyclohexanol in workplace air. Methods To collect the cyclohexane,cyclohexanone and cyclohexanol from the workplace air by pumping the air through the active carbon tube,resolve them with alcohol and then test the content of them by capillary gas chromatography. Results It was proved that these samples were separated effectively. The final measurement range of cyclohexane,cyclohexanone and cyclohexanol was 30-1 000 ?g/ml,20-1 000 ?g/ml and 20-880 ?g/ml respectively,the linear equation was y=257.4x+987.1 (r=0.999 9),y=239.9x+664.6 (r=0.9999 ) and y=192.4x+607.1 (r=0.999 9) respectively,the detection limit of was 1.5 ?g/ml,0.5 ?g/ml and 1.0 ?g/ml respectively. The minimum detectable concentration was 1.0 mg/m3,0.3 mg/m3 and 0.7 mg/m3 respectively (collected 1.5 L air sample). The efficiency of resolution was 90.1%,91.2% and 93.1% respectively. Conclusion The method is suitable for the simultaneous determination of the cyclohexane,cyclohexanone and cyclohexanol in the workplace air.
