Researching the Influence of Repeated Using to the Migration of Residue Bisphenol a from Polycarbonate with GC-MS Technology

Abstract:

Content of residue bisphenol A from polycarbonate (PC) was measured used the technology of gas chromatography-mass spectrometry (GC-MS). Dichloromethane was used as solvent and methanol was used as precipitating agent. The solution was rotary evaporation after the polymer was filtered. The simple, rapid, sensitive and accurate method of external standard which linear range is 0.05-200.0mg/L, standard addition recoveries is 90.8% ~94.2% and RSD is 3.2% -4.5% was used to quantitative analysis. The influence of repeated using to the migration of bisphenol A was also studied in this experiment. The results show that with the reusing times increased, the migration content of bisphenol A was gradually reduced which reduced to 0.75mg/L at the sixth time from 2.4mg/L at the first time.
