建立饮用水中一溴二氯甲烷的方法,考察平衡温度和平衡时间对一溴二氯甲烷测定的影响。实验结果表明,一溴二氯甲烷的回归方程的线性相关性良好,方法最低检出限为0.01mg/L,加标回收率在93.8%~104.2%之间,符合分析测试要求。该方法操作方便快捷,测定结果准确,精密度高,检出限低,可满足于饮用水中一溴二氯甲烷的测定。
To establish a method for the determination of bromodichloromethane in drinking water, examine the effects of equilibrium temperature and equilibration time on the determination of bromodichloromethane. The experimental results showed that the linear correlation of the regression equation of bromodichloromethane was good. The minimum detectable limit of the method was 0.01 mg / L and the recoveries of spiked samples ranged from 93.8% to 104.2%, which met the analytical requirements. The method has the advantages of convenient and quick operation, accurate determination result, high precision and low detection limit, and can be used for the determination of brominated dichloromethane in drinking water.
