ABSTRACT
Objective To establish a rapid,accurate and sensitive method for the determination of toluene diisocyanate(TDI) in plastic playground.Methods The samples were distilled continuously for 12 hours by acetone at 80-85 ℃ in water bath,and after centrifuged,precipitated and filtered,separated by using GC1490,7% SE-30 column,the contents of TDI in the samples were determined by gas chromatography.The qualitative and quantitative analyses were carried out by the retention time and peak area respectively.Results The linear range of the method was 0.001 30-0.043 80 mmol/L.Regression equation was y=28 612x-29.336,with r=0.999,and the limit of detection was 0.001 30 mmol/L.The rates of recovery ranged 100.8%-103.6%,with RSD of 5.7%.Conclusion The developed method was rapid,accurate,sensitive and is applicable to the determination of TDI inplastic playground.
