摘要
应用GB/T5750.8-2006《铜试剂亚铜分光光度法》对饮用水源水中丁基黄原酸盐的测定进行了系统的探析。探讨了运用该方法测定饮用水源水中丁基黄原酸盐进行的一些技术问题。在标准分析方法的基础上,选用最新生产的合格的化学试剂,适当改进相关操作步骤,利用无水硫酸钠粉末干燥有机相层并破除乳化现象,能够确保水样丁基黄原酸盐测定的精密度和准确度。
Combined with the work practice of environmental monitoring, the application of the national standard classical analytical method-cupron-cuproine speetrophotometric method（GB/T5750.8-2006） to the determination of butyl xanthate in drinking source water was explorated systematically. On the base of standard method,chosing the latest produced and qualified chemical reagents,making appropriate improvements to the interrelated operating procedures,drying the organic medium phase and breaking through the emulsification in organic medium phase by the usage of decahedrons sodium sulfate powder, which can guarantee the accuracy and precision in the determination of butyl xanthate in water samples.
