摘要
采用紫外分光光度法测定废水中微量油,同国标法(GB/T1648-1996)相比,操作简单。所使用的萃取剂正己烷可减少对人员的伤害。使用浓硫酸磺化和蒸馏相结合提纯溶剂的方法,可节省实验准备时间。
This paper studied the determination method of oil content in wastewater. Compared with the national standards, the method using n-hexane as an extractant has little injure to lab assistant and is easy to operate. The time of trial preparation would also be decreased by purification method combined with sulfonation and distillation.
