| Abstract: |
| A headspace gas chromatographic(HS/GC) method was established for the determination of volatile benzene and benzene homologues in eraser.The sample pretreatment and chromatographic conditions were optimized.After properly crushed,the sample was detected by HS/GC,and the result showed that this method had the advantages of saving solvent,environment friendliness,rapidness and simplicity.The linear ranges of 8 volatile benzene and its homologues were in the range of 0.05-5.00μg/g,with correlation coefficients more than 0.999.The detection limits were in the range of 0.02-0.04μg/g,and the average recoveries were in the range of 91.9%-98.9% with the relative standard deviations less than 5%.Market monitoring analysis showed that the contents of the volatile benzene and its homologues in different brands and different kinds of erasers were quite different.And it was still imperative to increase the safety supervision on this kind of products though the market was relatively safe. |
