Abstract:
Objective To establish a gas chromatography method which will be suitable for determination of one time of the benzene, toluene, dimethylbenzene in the adhesives. Methods DMF was used for dissolving the sample, polyethylene glycol chrom-atographic column, hydrogen flames detector gas chromatography were employed to separate the compounds, determine the nature of serve time, quantify apex area. Results The contents of benzene, toluene, dimethylbenzene in gooey were 7.33-146.50, 7.23-144.50 and 7.21-144.20 mg/L respectively, with a good linear relativity (r=0.999), the rate of recovery were 96.45%-100.09%, 98.45%-100.76%, 97.81%-100.14%, the detection limits of the three chemicals were 0.22, 0.24 and 0.24 mg/L respectively, RSD were 1.60%-2.85% . Conclusion The method is accurate, feasible and suitable for determination of the benzene, toluene, dimethylbenzene in the adhesives.
