Abstract:

This paper establishes a separation and determination method for o-cresol,m-cresol and p-cresol with capillary gas chromatography.The peak area and concentration of o-cresol and m-cresol have linear relationship in the range of 2～200g/L,and the relative standard deviation is respectively 1.84% and 1.67%; the same of p-cresol has linear relationship in the range of 2～200g/L,and the relative standard deviation is 1.63%.The determined recovery rate of them are all between 96.4%～103.8%.
