Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is researching the determination method of trace and trace amounts of chloroform and carbon tetrachloride in water. The method utilizes the weak solubility of chloroform and carbon tetrachloride in water, and uses stationary headspace gas chromatography to perform trace and trace analysis using a DC550 column. The results showed that trichloromethane ranged from 0.00 to 20.0 μ G/L concentration range, carbon tetrachloride between 0.00 and 1.00 μ There is a good linear relationship within the range of g/L concentration, with r values of 0.9998 and 0.9996, respectively, while the minimum detectable concentration of trichloromethane is 0.19 μ The minimum detection concentration for g/L and carbon tetrachloride is 0.01 μ G/L, with a recovery rate between 95% and 110%. Conclusion: This method has less interference and no secondary pollution. The method has been used for the determination of chloroform and carbon tetrachloride in mineral water, well water, purified water, and source water with satisfactory results.
