ABSTRACT
OBJECTIVE:
To establish a method for detecting triphenyl phosphate( TPP) in the workplace air by gas chromatography.METHODS:
TPP in the air of workplace was collected with glass fiber filter paper,desorbed with ether,separated by HP-5 gas chromatographic column,and detected by flame photometric detector.RESULTS:
This method has good linear range of 12. 50-800. 00 mg/L,with the correlation coefficient of 0. 999 9. The detection limit was 0. 78 mg/L,and the minimum detectable concentration was 0. 09 mg/m3(sample volume was 45 L). Desorption efficiency was 97. 2%-99. 4%; standard recovery rate was 99. 5%-100. 3%. The within-run relative standard deviation( RSD) was 2. 7%-3. 4%and the between-run RSD was 1. 4%-3. 2%. The sampling efficiency was 99. 6%-100. 0%. The samples could be stored at room temperature for at least 14 days.CONCLUSION:
The method is simple,accurate and highly sensitive for detecting TPP in workplace air.
