建立了高效液相色谱法测定工业废水中二甲基甲酰胺含量的方法,样品经玻璃纤维滤膜过滤,采用高效液相色谱法。本方法的线性范围相关系数>0.999 4,检出限为10μg/m L,样品加标回收率在95%~102%,标准偏差为1.83%,本方法处理简单、准确性高、快速稳定,适用于工业废水中的二甲基甲酰胺的测定。二甲基甲酰胺是一种化学性质稳定、沸点高、性能优良的无色有机溶剂,被广泛应用于皮革、纺织、医药和食品添加剂等领域的生产中。在大多数
A method for the determination of dimethylformamide in industrial wastewater by high performance liquid chromatography (HPLC) was established. The sample was filtered through glass fiber membrane and analyzed by high performance liquid chromatography. The linear correlation coefficient of this method is 0.999 4, the detection limit is 10 μg / m L, the spiked recoveries are 95% -102% and the standard deviation is 1.83%. The method has the advantages of simple processing, high accuracy, fast and stable, For industrial wastewater dimethylformamide determination. Dimethylformamide is a colorless, organic solvent with high chemical stability, high boiling point and excellent performance. It is widely used in the production of leather, textile, medicine and food additives. In most
