| 摘 要： | 目前 ,环保或其他部门对废水、气中的油的测定 ,一般采用石油醚萃取的重量法、红外或紫外分光光度法[1～ 5] 。因均需除去水分 ,步骤较繁琐。本法根据植物油在紫外区 2 0 0nm附近有强吸收 ,采用在废水中加入S T混合乳化剂进行乳化后 ,直接用紫外分光光度法测定其混合油的含量。方法简便快速 ,稳定性好 ,回收率在 89%～ 12 9%之间 ;线性范围为 :0～ 92 μg·mL-1。

| Abstract: | In this paper, the trace oil in sewage have been emulsified with S-T emulsifier and determined by ultraviolet spectrophotometry. Under normal temperature, the oil even dispersed in sewage with S-T emulsifier. It is stable and direct determined without separation. The oil is from sewage. The linear range is 0-92 micrograms.mL-1, and rate of recovery is 89%-129%. The method is quick and simple. |
