Abstract:
Objective To study the method for determination of micro and trace chloroform and carbon tetrachloride in wa-ter by headspace chromatography.Methods Based on the mild solubility of chloroform and carbon tetrachloride in water,trace chloroform and carbon tetrachloride in water were analysed by static headspace gas chromatography using an OV-101chromato-graphic column.Results The better linear ranges for chloroform and carbon tetrachloride were0.00-20.0?g /L(r=0.9998)and0.00-1.00?g /L(r=0.996)respectively.The detection limits of chloroform and carbon tetrachloride were0.19?g /L and0.01?g /L respectively.The recovery rate of the method was95%-110%.Conclusion The method could be satisfactorily used for determination of chloroform and carbon tetrachloride in mineral water,well water,pure water and source-water with the advantage of less interfering factors and no secondary pollution.
